Description Valorie Zimmerman 2010-05-30 01:40:49 UTC

Application: amarok (2.3-GIT)
KDE Platform Version: 4.4.3 (KDE 4.4.3)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-22-generic x86_64
Distribution: Ubuntu 10.04 LTS

-- Information about the crash:
Was checking out the Shoutcast streams and decided to quit. Amarok almost always crashes on close. I'll try with phonon-xine and see if that's still true.

Freshly built from git a few minutes ago.

The crash can be reproduced some of the time.

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

Sure enough, it does NOT crash under identical conditions using the xine backend. Same stream, same build - quit, no crash. Repeatedly.
