Bug 232175

Application: amarok (2.2.2)
KDE Platform Version: 4.4.1 (KDE 4.4.1)
Qt Version: 4.6.2
Operating System: Linux 2.6.32.9-70.fc12.i686 i686
Distribution: "Fedora release 12 (Constantine)"

-- Information about the crash:
Not much information that I can add, running KDE 4.4.1 under Fedora 12, up until a recent update to kdelibs everything was fine. Now it seems that Amarok is segfaulting at random while playing, doesn't appear to be influenced by any particular type of file, period of time, etc.

The crash can be reproduced some of the time.

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