Bug 273054

Application: plasma-desktop (0.4)
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:
Reproducably: When closing Kaffeine (while playing), the "Now Playing" widget will produce a crash. "Now Playing" never showed the current track anyway - some broken connection? The play/pause/forward/etc controls work, however.

- Custom settings of the application:
Kaffeine playing music from a playlist, "Now Playing" widget in the lower panel.

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma Desktop Shell (kdeinit4), signal: Segmentation fault
