Application: knetworkmanager (v0.9)
KDE Platform Version: 4.3.80 (KDE 4.3.80 (KDE 4.4 Beta1))
Qt Version: 4.6.0
Operating System: Linux 2.6.32-2-generic i686
Distribution: Ubuntu lucid (development branch)

-- Information about the crash:
Everytime I login to my system, knetworkmanager loads before plasma, and generates a bunch of notifications on the top-center of the screen. When I click on them to dismiss them, when I dismiss the last one or second to last one, knetworkmanager crashes. When knetworkmanager generates notifications with plasma running, when I dismiss them knetworkmanager does not crash,

The crash can be reproduced everytime.

 -- Backtrace:
Application: KNetworkManager (knetworkmanager), signal: Segmentation fault
