Application: plasma-desktop (0.4)
KDE Platform Version: 4.9.2
Qt Version: 4.8.3
Operating System: Linux 3.5.0-17-generic i686
Distribution: Ubuntu 12.10

-- Information about the crash:
- What I was doing when the application crashed:
1) Enable Grid desktop
2) Add Folder view plasmoid
3) Change settings for newly added forlder view
4) Click apply -> Plasma crashes

The crash can be reproduced some of the time.

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