Bug#532271: Horrible

[Debian]

NO - everything only just looks fine  till the next reboot!
After reboot KDE does not run any more!!!
Only the login screen is coming up and after trying to login the background is
remaining.

The Xorg.log is showing crazy problems with the mouse (cyrillic).
I don't know what has happened now?
An "apt-get -f install" and "apt-get check" is clean.

So at least the try of an upgrade has completely destroyed the installation.

I see no further chance to recover and will install an backup from march now. :-(
Then i will try another dist-upgrade.

The severity of this bug must be increased.
