Bug 284920

Application: plasma-desktop (0.4)
KDE Platform Version: 4.7.2 (4.7.2)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-13-generic x86_64
Distribution: Ubuntu 11.10

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

I was doing nothing particular. I had a couple instance of Dolphin opened and I activated suspend to RAM. When I reactivated my session, after I logged in unlocking the screen, I received this crash report. Actually, all seems normal, the desktop works normally and I noticed nothing particular.

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