[Fred-Barclay]

Brief Description

OS: Linux LMDE 2 "Betsy" 64-bit w/ MATE (based on Debian Jessie)
qTox version: Nightly
Commit hash: built without git
toxcore: 0.0.0
Qt: 5.3.2
Hardware: https://gist.github.com/Fred-Barclay/6fa531933e1d583457903103c7e1eaa7

Reproducible: Always

Steps to reproduce

1. Start qtox
2. Go to Settings >> Audio/Video
   

   Observed Behavior

The qtox window immediately exits and crashes.

Expected Behavior

Whatever normal behavior is! :smile:

Additional Info

Behaves identically to #1414. At first glance the gdb traces are different, though.

gdb trace: https://gist.github.com/Fred-Barclay/6c18019c26cbc271636e608e74d12969

No log file or qtox directory in ~/.config/tox

webcam info: https://gist.github.com/Fred-Barclay/97338d546d162d4928c243d2ee4967ef

Used apt-get and "deb https://pkg.tox.chat/debian nightly jessie" as the repo.

Thanks mates. :)

Could you try with https://software.opensuse.org/download.html?project=home%3Aantonbatenev%3Atox&package=qtox ?

IIRC repo should also have package for debugging symbols, you'd want to install it & then get backtrace – it should contain more useful info.

[zetok]

Oh, and btw, you'd want to do

t a a bt
t a a bt full

before quit in gdb.

[Fred-Barclay]

Thanks zetok.
I completely removed the old build, added the repo, removed the config and cache file in my /home, and installed and started qtox. I got the same result (a sudden crash) when going to Audio/Video. Would you like me to run it inside gdb and post the output here?

Would you like me to run it inside gdb and post the output here?

Yep, along with version info.

qTox version: eb743b4-obs
Commit hash: eb743b43ff10a86288259792c1f950dca045c8ef
toxcore version: 0.0.0
Qt version: 5.5.1

I also installed the debug symbols you mentioned.

Here's the gdb trace: https://gist.github.com/Fred-Barclay/64c93619964e8edc73e31bdd309395cc

t a a bt and t a a bt full run this time. I guess you can tell I don't normally use gdb? :)

[Fred-Barclay]

Well, qTox version v1.4.0-228-g9694d6b-obs isn't crashing any more, and I can change my audio and video options.
I'll give it a few days and if it stays stable I'll close this.

Thanks @zetok and cheers!

It's the weirdest thing... qtox will crash about half the time when I go to the Audio/Video option, but when I run it in firejail it hasn't crashed at all... yet. :smile:

[Fred-Barclay]

Qtox has been stable for about a week now, firejail or no firejail, so I think this can be closed for now. Thanks @zetok!
