Just another question.
When i try to swich users i always get a system crash, also if i try to first lo out and then log in with other user it's ok, but if i try to log out and log in again with the other user i get a crash.

So... the only good way for me to change user is to reboot system.

Is it a bug? of slackware 12 or of KDE ? or maybe am i an idiot?
