Comment 1 Dario Andres 2010-02-27 14:58:11 UTC

Mh, the backtrace is not really useful in this case...
- Have you tried to repeat the situation to check if DragonPlayer crash again (finish watching the same movie)?
Regards

Perhaps this crash report would be more helpful, except mine crashes when trying to *open* the wmv file:

Comment 3 Martin Sandsmark 2010-07-22 11:53:01 UTC

The first backtrace seems to end here:
http://qt.gitorious.org/qt/qt/blobs/4.7/src/gui/kernel/qapplication.cpp#line4298

Maybe a Qt bug?

Comment 4 Aakash 2011-11-21 16:31:45 UTC

Yes, it is a Qt bug.http://qt.gitorious.org/qt/qt/blobs/4.7/src/gui/kernel/qapplication.cpp#line4298 (CONFIRMED)

Comment 5 Myriam Schweingruber 2011-11-21 16:48:30 UTC

Closing, thank you for the triaging help :)
