Crashes only outside gdb.
Works fine with oxygen-gtk3-1.2.1, so what oxygen-gtk3 version recommended for using with gtk3-3.10?
Comment 1 Hugo Pereira Da Costa 2013-12-11 19:21:47 UTC 

*** This bug has been marked as a duplicate of bug 328488 ***
Comment 2 nucleo 2013-12-11 19:24:08 UTC 
Why this is duplicate?
1.2.0 and 1.2.1 version was fine, so this crash new for 1.3.0 version.
Comment 3 Hugo Pereira Da Costa 2013-12-11 19:25:33 UTC 
they are the exact same backtrace.
(please look)
I really suspect something upstream (gtk, or glib)
... and can't reproduce any of the two bugs ...
Comment 4 Hugo Pereira Da Costa 2013-12-11 19:37:01 UTC 
How exactly is this crash produced ? 
(the bug reports says: reproducible = always) ?
Comment 5 nucleo 2013-12-11 19:38:54 UTC 
Crash happens every time when guvcview started (outside gdb) and only with oxygen-gtk3 1.3.0 version.
Comment 6 Hugo Pereira Da Costa 2013-12-11 19:39:45 UTC 
Thanks
So definitly can't reproduce.
Also, the fact that it does not happen in gdb is very suspicious ...
Comment 7 Hugo Pereira Da Costa 2013-12-11 19:49:25 UTC 
Can you try compile guvcview manually and see if crash still happens ? 
(it is pretty easy to compile; just did so ...)

Backtrace for compiled manually last 1.7.2 version (previous 1.7.1 also crashes).
Comment 9 Hugo Pereira Da Costa 2013-12-11 21:21:52 UTC 
Created attachment 84052 [details]
proposed patch

Ok. Might not be the same bug as the other after all. 
This one should be fixed with the patch in attachment. Can you double check ? 
Uninitialized variable (damn ! that's a real newby mistake)
Also explains why it would not crash in gdb
Comment 10 Hugo Pereira Da Costa 2013-12-11 21:22:21 UTC 
... and that it does not crash on all systems. Depends how lucky you are at compile time ...
Comment 11 nucleo 2013-12-11 21:33:04 UTC 
No crash with 1.3.0 built with patch but I don't know about how was I lucky this time.
Comment 12 Hugo Pereira Da Costa 2013-12-11 21:34:40 UTC 
hopefully you're not.
At least the patch fixes a _real_ bug, that can result in crashes at the exact right place that what you had ...
Comment 13 Hugo Pereira Da Costa 2013-12-11 21:35:37 UTC 
Anyway. I'll push the change and will re-release (damn!)
thanks for reporting the issue and insisting.
