Right. Because the admin interface requires authorization. It seems that 
you haven't authorized yourself on that server/port yet. Any 
unauthorized access raises Unauthorized and you end up in pdb (instead 
of being deferred to a login screen). This isn't really grok's fault, 
this is just the way that the PostmortemDebuggingHTTP server works.
