Description Fadi R 2009-11-21 04:35:04 UTC
Application that crashed: plasma-desktop
Version of the application: 0.3

What I was doing when the application crashed:
Hi, this happens about daily. QuickAccess crashes Plasma. I am assuming that it is something in my setup that is conflicting with it. I have also submitted this bactrace report to the Develloper of the QuickAccess Widget. Does anyone know what it may be conflicting with?

The QuickAccess widget is probably trying to access an invalid URL/file and/or is in a broken state:

There is not too much KDE can do about this...
If the developer is aware of that issue, he/she will try to fix it.. you may need to provide him/her a better backtrace.
