Bug 208955

Application that crashed: plasma-desktop
Version of the application: 0.3
KDE Version: 4.3.1 (KDE 4.3.1)
Qt Version: 4.5.2
Operating System: Linux 2.6.30.5-43.fc11.i686.PAE i686
Distribution: "Fedora release 11 (Leonidas)"

What I was doing when the application crashed:
Whenever I disconnect my Windows Mobile phone (which is seen as USB networking device), the knetworkmanager plasma applet hits an assertion in dbus and thus makes  the whole desktop SIGABORT.
This is 100% reproducable, connecting is fine, disconnecting leads to the crash.
