Well, i tried that after booting into x86-2006.0-minimal. Unfortunatley,
that didn't solve my issuses; I found out that my system behaves after
the following pattern:

login with user1:
$ users
user1
$ exit

login with user2:
$users
user1 user2
$exit

login with user3:
$users
user2 user3

Thus, the system seems to ignore logouts as long as there are not more
then two additional logins.	

I've also did a reiserfschk while staying in the live-cd environment,
but no corruptions where found ...
