Bug 278886

Application: kded4 ($Id$)
KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-10-generic i686
Distribution: Ubuntu 11.04

-- Information about the crash:
- What I was doing when the application crashed:
Accesssing the internet. The 3G modem was disconnected by itself and then the system crashed.

- Unusual behavior I noticed:
The Network Manager refused the 3G internet modem and restart the system was needed.

The crash can be reproduced every time.

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