Description Clemens Eisserer 2010-10-08 13:21:00 UTC 
Version:           unspecified (using KDE 4.5.1) 
OS:                Linux

When I clicked disabled and the re-enabled wireless networking in the plasma-networkmanager-plugin I got the following crash.
Because there isn't a single line which mentions the plugin, I report this under "general":
