Bug 327297

Application: plasma-desktop (4.11.2)
KDE Platform Version: 4.11.2
Qt Version: 4.8.4
Operating System: Linux 3.11.0-13-generic i686
Distribution: Ubuntu 13.10

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

- Unusual behavior I noticed:
if a network cable connected is everything fine, if not the taskbar doesn't appear. Working/Using the Desktop would be possible but inconvenient. After connecting a network device(e.g. mobile phone with usb network possibility) the crash messages is appearing and a short moment later the taskbar is appearing

The crash can be reproduced every time.

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