Description Oliver Ney 2010-12-20 18:21:38 UTC

Application: amarok (2.3.2)
KDE Platform Version: 4.4.5 (KDE 4.4.5) (Compiled from sources)
Qt Version: 4.7.1
Operating System: Linux 2.6.34-gentoo-r12-ck1 x86_64
Distribution: "Gentoo Base System release 1.12.14"

-- Information about the crash:
Amarok crashed a few times already when I was connecting to a radio stream using a very weak WLAN connection which uses the fail at times.

The crash can be reproduced some of the time.

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

This looks like a problem with libxine, not much we can do about, sorry.
