Bug 280548

Application: plasma-desktop (0.4)
KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-10-generic x86_64
Distribution: Ubuntu 11.04

-- Information about the crash:
- What I was doing when the application crashed:
I were basically browsing net. Forums. I have noticed when Swap gets near full (I have 1GB swap & 1GB RAM) I have widget on desktop on which I see RAM and swap usage.

I have noticed when RAM usage is like ~900MB and/or Swap usage 750-900MB there is my mouse freezes to the point I cant do anything. Need wait few minutes and then it usually goes away.

There is possibility it is Amarok related - I just dont remember if Plasma crashed right after I closed Amarok or few minutes later..

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