[KDE 4.1 backports] login problems after yesterdays upgrade

[Grammostola Rosea <rosea.grammostola@gmail.com>]

Hi,

I'm using kde4.1 backports for a while now in Debian lenny. Yesterday 
there was a update.

But now I'm not able to log in anymore.

When it boots it comes in kdm, but when I log in, the screen is flashing 
but kde is not started, it jumps back to kdm.

When I do a konsole login and after that, startx. I enter Openbox (which 
I have also installed) instead of kde4...

I can't see any error messages..

What can be the problem here?

Thanks in advance,

\r
