Description: KDE 4.2 not running any more when installing one click
installer from Enterprise DB
Details:

Hi there,

I am running a Kubuntu 9.04 Jaunty OS. I wanted to check out the one click
installer from http://www.enterprisedb.com/getfile.jsp?fileid=570 - the file
is postgresql-8.4.0-rc1-1-linux.bin. Downloaded 2009-06-18 00:09. The
installation process is easy and working fine (no extra packages installed).
Also postgresql and pgAdmin is running fine. But after shutting down the
system, restarting it, giving username and password to the login prompt, kde
4.2 try's to start but crashes totally with the message (like) "Could not
start kdeinit. Pleasye check your installation". Ok - trying to run a save
session but no way. Then I uninstalled postgresql with the uninstaller
program, rebooting and everything works fine again.

I copuld not figure out what the problem is in more depth.

Cheers

Andy
