Public bug reported: Instead an error message appeared about qdbus. I then checked whether qdbus was correctly installed. I saw that only qdbus:i386 (in my amd64 system) was actually installed, so I proceeded to install regular qdbus. This replaced qdbus:i386 by the regular qdbus, which finally solved my problem. Now the KDE session starts without problems.
I hope this helps to fix the issue before the final release in April.
