Application: amarok (2.3.2)
KDE Platform Version: 4.5.3 (KDE 4.5.3)
Qt Version: 4.7.0
Operating System: Linux 2.6.35.6-48.fc14.x86_64 x86_64
Distribution: "Fedora release 14 (Laughlin)"

-- Information about the crash:
Clicking on the close button (in the title bar) of the main Amarok window causes it to crash.  This happens when Amarok is playing music and when it's paused.

The crash can be reproduced every time.

-- Backtrace:
Application: Amarok (amarok), signal: Segmentation fault
87	  int result = INLINE_SYSCALL (poll, 3, CHECK_N (fds, nfds), nfds, timeout);
