Application: plasma-desktop (0.4)
KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-11-generic i686
Distribution: Ubuntu 11.04

-- Information about the crash:
- What I was doing when the application crashed:
I had added an open, wireless connection (with "connect automatically"). While it was retrieving an IP address I deleted the remembered connection to the network I was currently trying to connect to. 

- Unusual behavior I noticed:
Plasma crashes. This happens every time I repeat the procedure. 

(This is similar to many other reports, but I did not find an identical one, and many of those issues do not seem to appear on my system)

The crash can be reproduced every time.

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