Authentication rejected on Kubuntu installation

[Mads Peter Rommedahl]

Hi all, I have a problem:
I just installed Kubuntu hardy Alpha 5 on my stationary pc (mounted the iso through Daemon-tools and installed it through the Wubi-thing).
Now, when I boot up I get to decide whether I want to start XP or Kubuntu. That sounds great, and I choose Kubuntu, it begins loading Kubuntu, and then it spits out a KDialog-error box reading:

"There was an error setting up inter-process communications for KDE. The message returned by the system was:

Authentication rejected, reason: None of the authentication protocols specified are supported and host-based authentication failed.

Please check that the "dcopserver" program is running."

Then I press OK, and a few seconds later the same dialog appears again.
I press OK on that one too, and then I get a new dialog saying that the installation failed, that logs have been saved at /ubuntu/installation-logs.zip (which I obviously can't access, since Kubuntu won't install) and that the system is now going to reboot.

I have tried a couple of times, and every time the authentication fails and the system reboots - what's going on?!

I can confirm this.

With Kubuntu Alpha5 desktop CD, I select 'Install Kubuntu'
When Ubiquity starts, there is an error message caused by dcopserver not running:

"Error setting up communication for KDE
Authentication rejected...
Please check that the "dcopserver" program is running."

ps -ef | grep dcopserver shows [dcopserver] <defunct>

When I click ok, I get a kwin crash report (not sure if it's caused by dcopserver having crashed)

hit enter, then I can go through the installer. not very pretty since kwin is not running.

cat /var/log/messages | grep dcop shows dcopserver_shut segfault error 4

not sure which package this should be assigned to

This bug was mentioned in the caveats section of the release notes and it was fixed in ubiquity 1.7.11. Please try a newer ISO, such as the Alpha 6 CD.
