Comment 1 Dario Andres 2009-12-12 22:45:09 UTC

This could be related to bug 217392.
- Have you noticed that you are using kdelibs from KDE 4.4 and kdebase from 4.3.4 ? It is not an ilegal combination, but it will be best to have both modules at the same version.

Comment 2 Arne Babenhauserheide 2009-12-12 23:50:22 UTC

plasma-workspace 4.3.80 didn't build, because pykde4 4.3.80 didn't built. 

Building plasma without python allowed me to get version 4.3.80 and now it works. 

Also I updated kdebase-startkde to 4.3.80, which might be related, too. 

Sorry for the noise...
