Bug 308347

Application: plasma-desktop (0.4)
KDE Platform Version: 4.9.2
Qt Version: 4.8.2
Operating System: Linux 3.2.0-32-generic i686
Distribution: Linux Mint 13 Maya

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

My Wifi was hanging and a webpage was not loading so I removed and reinserted my WiFi dongle (D-link DWA 130) in order to reboot it. This promptes a crash of OS and a bug report window came up. I've experience similar crashes, only on Linux systems.

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