Description Bernhard Jungk 2011-04-18 17:59:22 UTC
Application: plasma-desktop (0.4)
KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-8-server x86_64
Distribution: Ubuntu Natty (development branch)

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

Suspend to RAM somtimes causes kded4 to hang (100% cpu load). I did not find out the root cause of this problem, but the only thing that helps is killing kded4 and restarting it. This in turn causes plasma to crash and restart.

It could be related to changes of attached hardware (different usb sound card after waking up) or to the network manager (different network after waking up).

The crash can be reproduced some of the time.

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