We had it about problems with NVidia drivers before, but I do not use 
NVidia cards, so I do not care about the details.

It seems you are running KDE as root user:

kdeinit4_wrapper: Warning: connect(/root/.kde/socket-STEPHAN/kdeinit4__0) 
failed: : No such file or directory
Error: Can not contact kdeinit4!

I strongly recommend that you use a regular user for it.

On a first glance both xsession-errors looked quite simular to me. Are you 
sure you got the right one for the good case?

The other things I found:

- Could not connect to D-Bus server: org.freedesktop.DBus.Error.NoServer: 
Failed to connect to socket /tmp/dbus-T2YWVptAcv: Verbindungsaufbau 

=> But thats even in the ok case. Is dbus running at all? KDE 4 heavily 
relies on DBUS.

- wicd-client seems to segfault, maybe try with deinstalled wicd-client? 
Which one do you have installed? The kde or gtk variant?

- Akonadi does not be able to start the MySQL database server... did you 
install mysql-server-core-5.1 or something like that?
