Application: plasma-desktop (0.4)
KDE Platform Version: 4.9.4
Qt Version: 4.8.3
Operating System: Linux 3.5.0-22-generic x86_64
Distribution: Ubuntu 12.10

-- Information about the crash:
System is dualboot w/Win8, Kubuntu installed last. I am a vitrual Linux n00b, but have been a PC user for 20+ years (Apple][, then MS-DOS/WIndows since Dos 3.0). 
After running Kubuntu for several days, booted to Win8 for a few hours. On reboot to Kubuntu, got a crash saying (I believe_) thatn the Plasma desktop crashed. Tried to ctl-C, log out, then manual login (I have Kubuntu set to auto-login). Same result then, and on subsequent syatem reboots.
No changes were made to the system, hardware or software, when switched to Windows. System should be identical to when Kubuntu was healthy and running.
Please contact if more info needed

The crash can be reproduced every time.
