Description Pétur Runólfsson 2010-03-22 22:30:45 UTC 
Application: amarok (2.3.0)
KDE Platform Version: 4.4.1 (KDE 4.4.1)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-16-generic x86_64
Distribution: Ubuntu lucid (development branch)

-- Information about the crash:
This happened when shutting down Amarok through the menu (Amarok -> Quit), but it is not easily reproducible. I have seen crashes with a similar stack trace when modifying dynamic playlists. This seems to have started after upgrading to Lucid Lynx beta 1, I don't remember it happening in Amarok 2.3.0 or earlier versions in Karmic.

 -- Backtrace:
Application: Amarok (amarok), signal: Segmentation fault

Comment 1 Dario Andres 2010-03-22 22:58:00 UTC 
It seems also related to the Oxygen style...
Comment 2 Hugo Pereira Da Costa 2010-03-22 23:27:03 UTC 
mmm. well, yes and no. It happens at the deletion of a QPixmap when deallocating the style, but that's where it should happen ... (and we do delete _a lot_ of pixmaps when deallocating tilesets). Now QPixmap are implicitely shared objects. Probably there is some double deletion involved here (though not apparent in the backtrace), possibly due to some race condition. I'd rather think its a Qt bug ...
Comment 3 Pétur Runólfsson 2010-03-22 23:42:10 UTC 
Here is another stacktrace. This one came while modifying a dynamic playlist.

Comment 4 Hugo Pereira Da Costa 2010-03-23 22:25:45 UTC 
After double checking the code, there is no explicit pointer creation or deletion in the TileSet class (which deletion is responsible for the crash). Meaning that it cannot be (unless I misunderstand the basic of c++) an oxygen bug. Rather a Qt bug, being messed up when deleting "implicitely shared" pixmaps.
Comment 5 Mark Kretschmann 2010-04-16 09:45:35 UTC 
I'm sorry, but as Hugo pointed out, this does not seem to be an Amarok bug, but rather a bug in Qt or so.

Closing this report here. Please make a report at the appropriate place instead, thanks.
