My system (this crash is also confirmed on F23 systems of friends):

uname -a

[neteler]

FWIW, the last but one stable works fine on my system:

wget https://updates.tdesktop.com/tlinux/tsetup.0.9.18.tar.xz
tar xvfJ tsetup.0.9.18.tar.xz
./Telegram/Telegram

[tanty]

Same here, last but one stable works fine on Ubuntu 14.10.

Latest, SIGSEVs when clicking in the notification bar in GNOME Shell to try to rise the context menu.

This is how it started: $ ./Telegram Fontconfig error: "/etc/fonts/conf.d/10-scale-bitmap-fonts.conf", line 70: non-double matrix element Fontconfig error: "/etc/fonts/conf.d/10-scale-bitmap-fonts.conf", line 70: non-double matrix element Fontconfig warning: "/etc/fonts/conf.d/10-scale-bitmap-fonts.conf", line 78: saw unknown, expected number Fontconfig error: "/etc/fonts/conf.d/10-scale-bitmap-fonts.conf", line 70: non-double matrix element Fontconfig error: "/etc/fonts/conf.d/10-scale-bitmap-fonts.conf", line 70: non-double matrix element Fontconfig warning: "/etc/fonts/conf.d/10-scale-bitmap-fonts.conf", line 78: saw unknown, expected number Segmentation fault (core dumped)

And a backtrace from GDB: gdb.txt

[niklaas]

Had the very same problem. Running ./Updater from the command line solved the issue for me.

[tanty]

Not here.

Updater only checks and installs an update. Since this is happening with 0.9.24 stable and there is no other updates, it will only launch 0.9.24, which keeps SIGSEVing.

[tanty]

Checked all the latest dev versions. The regression was introduced between 0.9.19 and 0.9.20

All the 0.9.2x versions SIGSEV when trying to raise the context menu from the notification bar.

[niklaas]

You're right, my response was too fast. Yet, sometimes I get Telegram running by starting the updater.

[sgomez]

Same problem with Ubuntu and Gnome Shell. The problem appears when I try to open the contextual menu in the tray icon.

[Aokromes]

1630 very likely related to the recent glibc changes.

[diazbastian]

Here the same problem in fedora 23 64 bit (TDesktop stable and dev version)

[zeorin]

+1 Same problem on 64 bit Debian 8 Stable. Segfault when trying to use systray icon.

[telegramdesktop]

@neteler @tanty @niklaas @sgomez @Aokromes @diazbastian @zeorin Well, if someone is ready to help me with testing (I'll build new versions -- something between 0.9.19 and 0.9.20 -- and ask you to run them), you can contact me at telegram.me/preston through https://web.telegram.org (for example) and I'll send you .tar.xz binaries for testing there. But I don't know how long this will take because there were alot of changes, and each build (if we take Release optimized builds as close as possible to the ones that are distributed through site) takes about 20 minutes %)

The more guys will try a test build before deploying a new version the better.

[sgomez]

@telegramdesktop It's working fine on 0.9.25-dev. Thanks!

[telegramdesktop]

Please check out the latest 0.9.25 dev version from the bottom of this page:

https://desktop.telegram.org/#dev-version

It should be fixed there (e.g. if 0.9.18 worked fine for you, this one should be working as well).
