xserver-common removes every non-common package

[Harald Reider <harald@reider.at>]

Hello!

I updated X to resolve some gtk 1 font problems, and it worked.
However, the nvidia driver was deleted and cannot be installed anymore. It 
depends on xserver-common, but xserver-common would delete every kde package 
and many more (about 300 packages).

I don't understand why xserver-common deletes everything except common stuff. 
I would say this package is useless in its current state and also the 
depending packages (like the nivida driver).
