Bug 259588

Application: amarok (2.3.2)
KDE Platform Version: 4.4.4 (KDE 4.4.4) "release 3"
Qt Version: 4.6.3
Operating System: Linux 2.6.34.7-0.5-pae i686
Distribution: "openSUSE 11.3 (i586)"

-- Information about the crash:
interesting effect: when I start "strace amarok" instead of starting amarok directly, the crash does NOT happen??

The crash can be reproduced every time.

 -- Backtrace:
Application: Amarok (amarok), signal: Floating point exception
