Description of problem:

In the case of certificate verification failing, I get this gunk, when
I should get a nicer message with the same meaning.  This traceback,
for example, was generated because the date on the box was off by
about a month. :-P

[root@vmware4 rhn]# rhn_register --nox
Traceback (innermost last):
