Description benoit.leffray 2011-03-14 00:57:54 UTC
Application: plasma-desktop (0.3)
KDE Platform Version: 4.5.1 (KDE 4.5.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-22-generic x86_64
Distribution: Ubuntu 10.10

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

I happened to be running the system monitor while playing with this app.

I was scrolling down very quickly through the wallpapers. I could see the CPU load going rather high in the system monitor. 
It was also using a lot of ethernet bandwidth to download the wallpapers as I went.
A few seconds before the crash, I noticed a slowdown in the UI. But it  recovered after about 5s. I then went on scrolling down at the same pace, and got this crash.

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