Public bug reported:
Binary package hint: kubuntu-desktop
Bug appears in Kubuntu Dapper.
Can't switch user through KDE's menu "Switch User->Start New Session".
My system freezes after I press "Start New Session". First it switches
to text console and than t hangs up. Nothing helps after it - I even
can't reboot with Ctrl+Alt+Del.
I don't really know what backtraces could help there.
What information about my system is necessary.
Here are the things that maybe helpful:
