Xubuntu installation hangs up when removing conflict causing files

[Thomas82]

This isn't the only time I encountered this bug. I have Debian installed on separate partition. To be sure its config files don't interfere with installation I whiped clean partition /home. Installation hanged up at user creation screen. The same problem persisted no matter how many times I tried to install Xubuntu. Now when I try to install it, it hangs up even earlier, but that might be caused by Debian's files at /home partition.

Distro:
Description: Ubuntu precise (development branch)
Release: 12.04

Plus, when I check which process is using the most of CPU power, Ubiquity keeps growing in size.

@Thomas82 : Is this a duplicate of bug #909179 ?

Yes. I believe it is. Sorry, I couldn't find anything about it so I thought I will send in a bug report. You can delete this report if you wish.
