Bug 247540

Application: amarok (2.3.1)
KDE Platform Version: 4.5.00 (KDE 4.5.0)
Qt Version: 4.7.0
Operating System: Linux 2.6.34.3-37.fc13.x86_64 x86_64
Distribution: "Fedora release 13 (Goddard)"

-- Information about the crash:
- What I was doing when the application crashed:
Every second start of amarok it crashes. When you hit "restart application" from the crash handler it starts fine. Normally you could quit amarok then and on the next start all is working normally. But the start after that it crashes again.

If it matters: amarok is compiled based on the fedora package with this patch included: https://bugs.kde.org/show_bug.cgi?id=235030#c8

-- Backtrace:
Application: Amarok (amarok), signal: Segmentation fault
82	T_PSEUDO (SYSCALL_SYMBOL, SYSCALL_NAME, SYSCALL_NARGS)
