Comment 22 for bug 187918

I don't use ldap but I have a very similar problem ...
When I choose a KDE4 session, the splash appears , the HD icon for 45s, then the Settings icon for 4 or 5 minutes and eventually I get the the kdm blue background with the cursor but that's all...
This behavior appeared just the day before the upgrade from 4.1b1 to b2 ...

Additionaly I cannot run an KDE4 app inside KDE3 it crashes

Exemple trying to run Kopete :
----------------------------------------------------------------------------------------------------------------------------------------------------------------
philippe@kubuntu:~$ /usr/lib/kde4/bin/kopete
kopete(6626) KToolInvocation::klauncher: klauncher not running... launching kdeinit

and there it's stuck

the D-Bus message brought me here
I tried the edsoncv solution (qdbus && /usr/lib/kde4/bin/startkde) but it doesn't work ...

KDE4.1 is totally dead for me so far ... need help
