Application: amarok (2.3.0)
KDE Platform Version: 4.4.2 (KDE 4.4.2)
Qt Version: 4.6.2
Operating System: Linux 2.6.34-rc5 x86_64
Distribution: Ubuntu 10.04 LTS

-- Information about the crash:
When I logged in, Amarok started automatically (as the session was being restored), and crashed soon afterwards.

Something that may be related: I installed a new kernel version, and my sound card is not working. KDE displayed a message "KDE detected that one or more internal sound devices were removed.".

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