In my now, ööh, 2-year, is it, experience with kde4, I have found, when upgrading to 
new releases, that it is best to either uninstall all plasmoids that are not included 
in kdeplasma-addons, or at least not to have them added to any desktop or panel until 
after the upgrade, otherwise, when you reboot, plasma-desktop quite likely will 
crash.

I don't know if this caused your crash.
