Bug 284284

Application: plasma-desktop (0.4)
KDE Platform Version: 4.7.2 (4.7.2)
Qt Version: 4.7.4
Operating System: Linux 2.6.40.6-0.fc15.x86_64 x86_64
Distribution: "Fedora release 15 (Lovelock)"

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

Plasma desktop crashes when the lan card em0 is activated or disabled and re activated in a active plasma desktop session. The lan card em0 is connected to a adsl2 router via a Ethernet cable. If the router is powered off or power cycled in a active Plasma desktop session, most of the time the desktop workspace crashes before the lan interface em0 is bought back.

The crash can be reproduced every time.

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