Qt: 4.6.2
KDE Development Platform: 4.4.1 (KDE 4.4.1)
The KDE Session Manager: 0.4

<In detail, tell us what you were doing  when the application crashed.>
I turned the computer on and logged in.
it never made it to the desktop.
the animation before the desktop loads was stuck at roughly 40% or less...
then it froze. so i clicked the screen to see if it would go away and maybe give me more information.
it crashed and i had no use of my keyboard. so i could not type.
i had to save this report to a file for later submission.
