Version: (using KDE 4.2.85) OS: Linux Installed from: SuSE RPMs The media player applet reproducably crashes the plasma-desktop right after a file has been fully played, not when it is stoped manually. I tested with mp3, avi and mpeg, both with xine and gstreamer backend, see the backtraces. Even from within the plasmoidviewer it crahses plasma, see the backtrace. I think there is a connection with the crashes I have with the mini player plasmoid (http://www.kde-look.org/content/show.php?content=95501). It doesn't crash after playing, but manipulating the volume or the settings crashes plasma in KDE 4.2 and 4.3, too. Unfortunately I don't get a backtrace with that plasmoid. For the widgets are very similar (e.g. I have the same video problems with both, see https://bugs.kde.org/show_bug.cgi?id=191696), it might be a more general bug in phonon or plasma.

I forgot one thing: For the mini player plasmoid when crashing I get in gdb an output "segmentation fault", pointing to /lib64/libdbus-1.so.3 (KDE 4.2.2 on 64-bit system) resp. /lib/libc.so.6 (KDE 4.3b on 32-bit system), but then X freezes completely.
The three backtraces are mostly the same: #6 0xb501aef6 in MediaSource (this=0xbfe1f4d8, rhs=@0x80c64) at /usr/include/QtCore/qshareddata.h:155 #7 0xa8662e76 in ??

Could you please install the debug symbols package for the "kdeplasma-addons"/"playground-plasma" packages? Thanks
Created attachment 33766 [details] backtrace of crash (with xine) with plasma-addon debug symbols I see there are still some symbols lacking, but I don't know which
@Cyril: the backtrace is good enough. Thanks!
