Bug 192533

Application that crashed: plasma-desktop
Version of the application: 0.3
KDE Version: 4.2.85 (KDE 4.2.85 (KDE 4.3 Beta1))
Qt Version: 4.5.1
Operating System: Linux 2.6.29-ARCH i686

What I was doing when the application crashed:
Hi, im using arch with kdemod-unstable. 
When i upgraded to KDE 4.3 beta 1 (4.2.85) i had to do it with the force upgrade option because of some conflicts in the files (i could find the exact conflicts but with the other pc tomorrow). I've done forced upgrades before and never had a problem.
After the upgrade finished i rebooted the machine and i wash "thrown" to a terminal because kdm didnt start, so i started the session with startx and everything was ok. After a second reboot i got this plasma crash right after the session is loaded so i never get to see my desktop.
Everything is working fine aside from plasma, so i can run applications with krunner and switch between them as i would normally do.
Please help
