Description of problem:
If you try to register a system using rhn_register (the gui portion of
the component) several things go wrong:

1.  You get a series of glade warnings
2.  When you enter your username/password/etc on the required screen,
a dialog message comes back saying that you must enter a username
(which is already done).

I am pasting the warnings from the command line below, and attaching a
screenshot of the error to this bug.
