Bug 321435

Application: plasma-desktop (4.10.4)
KDE Platform Version: 4.10.4
Qt Version: 4.8.4
Operating System: Linux 3.2.41-desktop-f x86_64
Distribution: SolydK

-- Information about the crash:
This crash appeared to be absolutely random, since I was just listening to music, but not using "actively" any program

- Unusual behavior I noticed:
After the crash, there was a small window (not resizeable). Clicking into that opened some programs currently in the taskbar.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Shell del desktop di Plasma (plasma-desktop), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
