Bug 253035

Application: plasma-desktop (0.4)
KDE Platform Version: 4.5.70 (4.6 >= 20100927) (Compiled from sources)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-ARCH x86_64
Distribution (Platform): Archlinux Packages

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

simply hovering the taskbar...
I'm guessing this new svg cashing stuff has an issue somewhere ^_^

The crash can be reproduced some of the time.

-- Backtrace:
Application: Plasma Desktop Shell (kdeinit4), signal: Segmentation fault
