Bug 254559

Application: amarok (2.3.2)
KDE Platform Version: 4.4.5 (KDE 4.4.5)
Qt Version: 4.6.3
Operating System: Linux 2.6.32.21-168.fc12.x86_64 x86_64
Distribution: "Fedora release 12 (Constantine)"

-- Information about the crash:
Was playing KCRW live stream at http://64.12.61.1:80/stream/1046 and switching to other streams until amarok failed to actually play the selected stream. As i've seen that problem before, I quit amarok and it crashed (which is what usually happens after such hangs).

I'm using Fedora's Amarok:
amarok-2.3.2-3.fc12.x86_64
amarok-libs-2.3.2-3.fc12.x86_64
amarok-utils-2.3.2-3.fc12.x86_64


The crash can be reproduced some of the time.

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