Google Apps - postmaster BUG ???

Well I'm not quite sure and I did't have any time to test it but writing postmaster as a user for google apps seams to cause a bug.

What happend was that the domain name was saved as an account but there was no valid user name that I could use now.

I've tried some workaround with "Forgot your administrator username or password?" but when i got to the password change there was once again no user name. So if someone test this please comment here and let me know.
