KDE 4.2 is in openSUSE

Be careful and backup your plasmarc file, as it was corrupted on my system
afterwards:
- all icons/programs placed on the desktop gone
- the 3 icons in the left corner right to KDE and "Workspace" gone as well

The problem was that in plasmarc: The URL parameter to these programs was
empty. After manually inserting all the URLs pointing to the respective
*.desktop files, the desktop looked about the same.

Cheers,
Thomas
