6 years ago Hello!
I cloned git repo and checkout to '3.0.3' (i have this version and i know that this version is buggy now) I run this command and i got icons.qrc But this is now XML file and i don't know what should i do next with its? I installed the Electrum through command line 'sudo pip3 install...' The Electrum installed to '/usr/local/bin/electrum' Should i copy this icons.qrc file to some directory (?) in system and run electrum again?
P.S. And i found the file '/usr/local/lib/python3.5/dist-packages/electrum_gui/qt/icons_rc.py' in my system. May be this info will help...
Thanks for answer!

6 years ago I have the same issue. But, when I use "pyrcc5 icons.qrc -o gui/qt/icons_rc.py" command, the error message is that:
pyrcc5: File does not exist 'icons.qrc'
Anyone could help me? I use the same system: Linux MInt 18.3 and have same the segmentation fault issue

6 years ago Hi!
I did:
pyrcc5 icons.qrc -o gui/qt/icons_rc.py sudo cp gui/qt/icons_rc.py /usr/local/lib/python3.5/dist-packages/electrum_gui/qt/icons_rc.py
After i had run Electrum and got same error again Here is backtrace after rebuilding icons_rc.py an updating one.
I can try to update to 3.0.5 version (it's buggy 3.0.5) Or may be do you want to ask me to do some other tests for a catching this bug?

6 years ago @Perlover the bug seems related to Mint, then. I think we should close the issue here, because I dont see how we can fix it on our side
Perlover
commented
6 years ago May be. I have same Linux Mint 18.03 at work and there was Electrum 3.0.3 but i didn't have there problem. May be installed incorrectly cython-hidapi or hidapi library to python (i had problem when i installed at home). I close this ticket. I will try to reinstall Electrum and related libraries. If bug will not gone away i will reopen ticket.

commented
6 years ago Interesting noticeing
I updated Electrum 3.0.3 -> 3.0.5 The troubles were be continuing I reinstalled many modules (related with qt5 - python modules + deb packages) Troubles were there again
But when i copied ~/.electrum/wallet/* files and removed ~/.electrum (rm -rf ~/.electrum) and restored all wallets from copies (before i did again default_wallet in first start) - electrum works more stability (but i saw one crash)
So i think some file(s) in ~/.electrum caused Segmentation Fault

6 years ago Removing and recreating new ~/.electrum doesn't help :( May be problem was related with watch-only wallets for Bitcoin Trezor device. Now i have again - Electrum 3.0.5 crashed every time (not 100% cases but may be 90%) :(
Perlover
commented
6 years ago Here new gdb backtrace: Can you see again to this problem? If you cannot understand the reason of this bug i will close ticket. But i did many reinstalling and problem occurs again and again :(
P.S. I can recompile or rebuild Electrum with options you will ask for getting more debugging info if you need. Only please write which options?

6 years ago And i tested now not watch-only mode for Trezor Here native Segwit wallet for Electrum There crash again. But quickly sight to this shows that backtrace dump a little shorter

6 years ago I'm not sure what we can do to solve this. It seems like you're using a buggy Qt5 version, especially since the same issue occurs with other Qt applications.
I suggest you report this to your package maintainer.

6 years ago Here my other Linux MInt 18.3 computer and Electrum 3.0.5 There were rarely crashes but they were Now i catched core file in my work computer. Here backtrace, may be it will help anybody I will close this ticket but i think dumps can be usefull for somebody
It turns out that the reality now is that Electrum can not be used in Linux Mint 18.3 :(

6 years ago I've downloaded Linux Mint 18.3 with Cinnamon and tried to reproduce this to no avail. Does this happen deterministically when doing something specific?
Perlover
commented
6 years ago Hi, SomberNight!
Thanks for helping I have two computers: work & home. Both installed separately. But both had Mint 18.2 (Cinnamon) and after i upgraded successfully up to Mint 18.3 (Cinnamon). In both i installed by "sudo pip3 install" from "Download" section os Electrum site. First i had normal working Electrum at work and stability crashed at home. But in last time i see ofen crashed in work too. In both places i use Trezor watch-only wallets. But i saw that Electrum crashed in native wallets of Electrum too. I think it crashed when i use used wallets (which have a some transactions not empty). If i will notice some conditions for this bug i will let you know of cause here.

6 years ago Can you reproduce the bug when running PyQt in valgrind? This should show you where the cause of the segmentation fault is actually happening.
Perlover
commented
6 years ago I think i now reason of my problems
I installed now v3.1 and Electrum started without segmentation faults but it prints at start about trezor library version ("Your trezor library version is unknown but need 0.9.0") I tried to install again from https://github.com/trezor/python-trezor new v0.9.1 but after i got again and again this warning.
After i located in /usr/local/lib/python3.5/dist-packages these directories:
trezor-0.7.16.egg-info trezor-0.9.0-py3.5.egg trezorlib
I removed theirs by rm -rf ...
After i installed again python-trezor by "sudo -H pip3 install trezor" from source of python-trezor and now Electrum works. I didn't get SegFault but before it i got SegFault every time...
I think the problem was related with these libraries and may be by two versions of Trezor.

6 years ago Ohh, no... After some sucessfully runs the Electrum 3.1 now terminated by Segmentation Fault again ,,,
