Application that crashed: plasma-desktop
Version of the application: 0.3
KDE Version: 4.2.96 (KDE 4.2.96 (KDE 4.3 RC2))
Qt Version: 4.5.2
Operating System: Linux 2.6.30-1-amd64 x86_64
Distribution: Debian GNU/Linux testing (squeeze)

What I was doing when the application crashed:
My previous bug-report was https://bugs.kde.org/show_bug.cgi?id=201434
so I have updated python-kde4 to version 4.2.96-1
then made "plasmapkg -i mpd-plasma.plasmoid"
then tried to add this plasmoid to desktop and got plasma crash. :(
