Application: amarok (2.3.2)
KDE Platform Version: 4.5.1 (KDE 4.5.1) (Compiled from sources)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-23-generic i686
Distribution: Ubuntu 10.10

-- Information about the crash:
the usual trying to get amarok to play. I do not think I can give you more information than that except to say code 11 segmentation faults are much heavier than usual, averaging one every thirty seconds over athirty minute interval. Also, for some reason, quite a number of code 6's have shown up, which is something they never used to do.

The crash can be reproduced every time.

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