Comment 3 for bug 376421

I have the same problem since the kde 4.2.3 from ppa

Description: Ubuntu 9.04
Release: 9.04

2.6.28-11-generic #42-Ubuntu SMP Fri Apr 17 01:57:59 UTC 2009 i686 GNU/Linux

This morning :

sudo adept manager pops up a windows saying "could not start ksmserver.check your installation"
Thought It was a short disfunctionment ! No it is a bug each time I type now "sudo kate sth"
I read :

and then xmessage windows pops up. If I click "ok" the xserver reboots !
