[hobbit] Critical Systems page displaying "Internal Server Error"

[Gary Baluha]

I seem to be on a roll with weird problems lately.  I just found out that
the Critical Systems page doesn't load at all if I zero out the
hobbit-nkview.cfg file.  At least, not in a typical browser.  If I curl or
lynx the critical systems page from the command line, it loads okay.  It
just doesn't load in a graphical browser.
