Bug 255170

Application: kded4 ($Id: kded.cpp 1156841 2010-07-29 19:59:05Z zander $)
KDE Platform Version: 4.5.1 (KDE 4.5.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-22-generic i686
Distribution: Ubuntu 10.10

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

Just came out of suspend on laptop running KDE on Ubuntu 10.10 (kubuntu). Unable to connect to wireless network, I attempt to disable wireless and networking using plasma network-manager widget. 

- Unusual behavior I noticed:

Clicking wireless network connection from list provided by tray widget immediately fails and goes back to "configuring interface" status

- Custom settings of the application:

Wireless connection is hidden, so user must rely on automatic connection routine that seems to happen reliably at boot/login of KDE.

The crash can be reproduced every time.

-- Backtrace:
Application: KDE Daemon (kdeinit4), signal: Segmentation fault
