Application: plasma-desktop (0.4)
KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-8-generic i686
Distribution: Ubuntu 11.04

-- Information about the crash:
- What I was doing when the application crashed:
Searching for a character in Character Select - moving from screen Latin Extended B to Latin Extended Additional resulted in application crash. 

- Unusual behavior I noticed:
Only occurred between LE-B and LE-Additional, not other windows in the same application.

The crash can be reproduced every time.

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