Description Alex Merry 2009-12-21 15:05:16 UTC 
Application: dragon (2.0)
KDE Platform Version: 4.3.82 (KDE 4.3.82 (KDE 4.4 >= 20091211)) (Compiled from sources)
Qt Version: 4.6.1
Operating System: Linux 2.6.31-ARCH x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
I'm watching short (a few seconds to a few minutes) videos on a CD (ie: read-only media - I don't know if that's significant, but a couple of attempts from my home folder didn't do it).  Quitting dragon player (using the X in the title bar) just as the video ends appears to cause it to crash.

The crash can be reproduced some of the times.

 -- Backtrace:
Application: Dragon Player (dragon), signal: Aborted

Comment 1 Dario Andres 2009-12-21 15:17:08 UTC 
Looks like a Xine-FFMpeg related bug, but probably bug 196207.
Try this:
- Run Konsole
- Write "export MALLOC_CHECK_=" + Enter
- Write "export QT_NO_GLIB=1" + Enter
- Run dragon from Konsole
- Check if the bug can be reproduced

Thanks

I don't think it is a dupe of bug 196207, since I already run KDE with MALLOC_CHECK unset.  However, I can't reproduce it any more anyway (I updated my KDE trunk build and no longer have the CD of videos I originally had this problem with).

Mh, ok.. reopen if you experience this again. (btw, the variable to unset was "MALLOC_CHECK_" )
