Bug 281407

Application: plasma-desktop (0.4)
KDE Platform Version: 4.7.00 (4.7.0)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-11-generic x86_64
Distribution: Ubuntu 11.04

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

I was resizing a picture frame when Plasma crashed. The picture source was from internet, using HTTP - not local disk - I'm mentioning this because I saw kio in the crash dump.

I'm using Kubuntu 11.04 with KDE 4.7 from KDE's PPA.

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