Operating System: Linux 2.6.34.7-0.7-default i686
Distribution: "openSUSE 11.3 (i586)"

-- Information about the crash:
- What I was doing when the application crashed:
Amarok started sending a lot of "Cannot create I/O Slave" errors. When i opened the context menu for the icon to close it, plasma crashed. 

- Unusual behavior I noticed:
All those errors with amarok, they were a lot, like 20 (They opened and closed very fast).

-- Backtrace:
Application: Área de trabajo de Plasma (kdeinit4), signal: Segmentation fault
