Hi Fabian, 

maybe you could try to do an apt-get update (do not use aptitude for this 
time), so you might get a stable system. If this does not work, you might try 
to downgrade some packages or libs to testing. 

Downgrading to testing would be my very first idea, to get a stable system.
There is a blog, how to downgrade. Google will help you.

If it is running again, just upgrade your packages to unstable one after the 
other, so you might discover, which is the package, that makes problems.

Mixing testing and unstable is no good idea, except for applications which do 
not direct interfere withe the system itself (for example OpenOffice.org)

Good luck!
