thanks a lot! thats really nice from you!

another reason of not filing the bug was that i am in hollyday in a very
little village in the czech mountains with a lot of snow and a very slow,
sometimes no, internet connection. i have a brand new netbook with me, and
forgot to copy my username and password for bugzilla.novell.com to the new
machine.
i promise:handshake:i'll report the next bug correctly at
bugzilla.novell.com
