Bug 281266

Application: kded4 ($Id$)
KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-11-generic x86_64
Distribution: Ubuntu 11.04

-- Information about the crash:
- What I was doing when the application crashed:
when the connection stops working, unplugging and plugging the USB dongle often causes the program to crash.

The crash can be reproduced some of the time.

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