I was not able to reproduce this in 12.10. There are some different comments here about 12.04. Are you running gdm or lightdm? I wonder if this is a duplicate of bug #1064388?
The bug is in incomplete state now because there are unanswered questions. Anders, are you able to boot up a 12.04 live CD/USB stick and try to reproduce this on the server?
