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

When coming back to my computer I noticed the crash icon on systray. I am 90% it was not there when I left my computer.

I changed the usb wifi adapter and rebooted earlier in the day but I guess it has noting to do with this. Also akonadiserver crashes every now and then but it has not cause plasma crash.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
