Bug 161795

Please change the product from kcontrol to systemsettings or such. I searched for "kcmnotify" in the bug report wizard, that gave me two equal entries.

Could you post a backtrace following the instructions on:
http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports

Thanks a lot.

@Stefan: Please could you provide a backtrace with the -debug symbols?

KCrash output

Looks like it's in phonon

The second backtrace shows an XIO error handler in the main thread which calls exit() which makes the other thread crash. The crash in phonon_xine is a symptom of a different problem (i.e. the XIO error). From this information alone I can't see that any part of Phonon is "guilty".

Same problem for me (KDE 4.0.4, openSUSE 11.0, ).

David Geiger: your backtrace shows a bug introduced by an opensuse patch to phonon-xine. AFAICS this is not the same as the rest of this report.
