Description leonid.fainshtein 2011-11-14 11:52:09 UTC 
Application: plasma-desktop (0.4)
KDE Platform Version: 4.7.3 (4.7.3)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-12-generic i686
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed: Nothink special. It is enough to run Amarok or Clementine with the tray icon. The problem didn't happen in KDE 4.7.2

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