Bug 268515

Application: amarok (2.4.0)
KDE Platform Version: 4.6.00 (4.6.0) "release 6"
Qt Version: 4.7.1
Operating System: Linux 2.6.37.1-1.2-desktop x86_64
Distribution: "openSUSE 11.4 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:

Amarok ran normally. Only the Media Sources and Playlist views are enabled.
Clicked on "View", then "Context" - Amarok crashed.

Happens regardless of whether Amarok is playing music or not, and regardless of whether performing the action via mouse or keyboard.

The crash can be reproduced every time.

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