Tried just running directly and after the install instructions, get the same error.

$ python3 ~/usrbin/mcomix3/mcomix/mcomixstarter.py

OS: OpenSuse tumbleweed I also installed, python3-gobject, python3-gobject2, python-gtk, libgirara-gtk3-3 and python3-Pillow for the dependencies you said, but the same issue persists.

Sorry, I'm not familiar with opensuse. python3-gobject2, python-gtk and libgirara-gtk3-3 are not needed. Please ensure the packages are correctly installed and containing files like below:

/usr/lib/python3/dist-packages/gi/__init__.py
/usr/lib/x86_64-linux-gnu/girepository-1.0/Gdk-3.0.typelib
/usr/lib/x86_64-linux-gnu/girepository-1.0/GdkPixbuf-2.0.typelib
/usr/lib/x86_64-linux-gnu/girepository-1.0/Gtk-3.0.typelib
/usr/lib/x86_64-linux-gnu/girepository-1.0/PangoCairo-1.0.typelib

[moozaad]

opensuse paths are different.

/usr/lib64/girepository-1.0/Gdk-3.0.typelib
/usr/lib64/girepository-1.0/GdkPixbuf-2.0.typelib
/usr/lib64/girepository-1.0/Gtk-3.0.typelib
/usr/lib64/girepository-1.0/Pango-1.0.typelib
/usr/lib64/girepository-1.0/PangoCairo-1.0.typelib

gi is

<snip lots, just the top level>

/usr/lib64/python3.7/site-packages/gi/__init__.py

Spot any issues with that?

[moozaad]

nnadd was running with python2. If you explicitly use python3, it gives this output

python3 mcomixstarter.py 
Traceback (most recent call last):
  File "mcomixstarter.py", line 21, in <module>
    import mcomix.run
  File "/home/moozaad/bin/mcomix3-1.2.1/mcomix/run.py", line 32
    print constants.APPNAME + ' ' + constants.VERSION

SyntaxError: Missing parentheses in call to 'print'. Did you mean print(constants.APPNAME + ' ' + constants.VERSION)?

edit: I guess you've not releases yet then for python 3? These look like the original mcomics. I'll grab master and recheck.

edit2: yes that works fine here.

[nnadd]

I wish that was the problem.. I was using the instructions from the start..

This is using git clone https://github.com/multiSnow/mcomix3 tho

Tried the master here https://github.com/multiSnow/mcomix3/archive/gtk3.zip , still getting the same gtk segmentation error

[moozaad]

Sorry. Long day! Getting confused between the reddit info and this thread.

The question then is what is the difference between your install and mine? I had a quick look through a strace and couldn't see any calls or loads to anything with provider in the name.

Does look like it's touching this near a css load but that might be just enumerating the site packages. libcanberra-gtk3-module

[nnadd]

No idea, really I'm not the type to install a lot of packages in the first place, especially not ones with a lot of gtk3 libs that would change too much stuff.

[nnadd]

Did a strace of python3 mcomix/mcomixstarter.py The gtk errors are at the bottom..

dmesg seems has some info as well.

Are you running wayland? Could you try in a X session?

No dice, unfortunately. I was running X already.

"OpenSuse tumbleweed" that's a rolling release, they tend to be a bit unstable. The bug is probably in your system.

[marcosrdac]

I'm having the same issue on Arch Linux. Did you manage to solve the problem, @nnadd ?

I found the solution here. https://www.reddit.com/r/openSUSE/comments/bgt9y3/mcomix_stopped_working_after_tumbleweed_update/

EDIT: That's for python2 version, I haven't tried to fix the python3 problem, last I checked it didn't work

[marcosrdac]

Thanks for sharing! Although the error message was the same, my problem is actually with lightdm... I'm going to investigate it!

[vinyanalista]

I was facing the same error message (... assertion ... failed) with another application on openSUSE Leap 15.3.

What solved for me was installing the python3-gobject-Gdk package.

# zypper in python3-gobject-Gdk

[yhojann-cl]

Same error message when set application to window as ref using c++, the function only works without pointers and without after connect_activate(). Window need activate before build the window.
