Telegram-desktop crash on application start

Hey,

I am currently unable to start telegram-desktop. The application crashes when launched. I tried both telegram-desktop 2.8.11-2.0 and telegram-desktop-manjaro 2.8.6-1. After a fresh install I can get past authentification, but the application crashes directly after that. I get the following output when launching telegram from the command line (for both packages):

(telegram-desktop:20109): Telegram-WARNING **: 21:23:52.437: Application was built without embedded fonts, this may lead to font issues.
[ALSOFT] (EE) Failed to set real-time priority for thread: Operation not permitted (1)

Where error: : cannot open is when the crash happens. Here is the corresponding core dump:

Any suggestions?

Is your system fully updated? Seems to be a problem when calling glibc. The errors that are shown can be ignored.

Yes, my system is fully up-to-date. My version of glibc is 2.33-5.

Ok. Sorry but that’s all I can think of. Do you see more information in the logs? journalctl -b -xe, because right now there is not enough information to solve the problem.

Here is the output of journalctl -b -xe. I limited it to the relevant part, because my message would be too long otherwise.

Thanks for your help. Let me know if there is anything I can do or provide from my side.

I see you have a bunch of UFW BLOCK’s in there. Can you try disabling the firewall and launch Telegram, to see if that helps?

If it does, you might need to add a rule to UFW to enable Telegram to go through.

That does not seem to help, same results when ufw is disabled. Here is the journal with ufw disabled

I tried out telegram from flatpak with the following results:

2.8.11 : crashes
2.9: works fine

Ok, so todays update to telegram-desktop 2.9.0-4 has indeed fixed the issue for me.
