This Location header is invalid!  The HTTP specification says only
absolute URIs are allowed here.  That's the cause of the redirect being
rejected.

I've never seen this message as being connected to the removal of a
document before, but I guess when you completely empty out the database,
that would do it.  I don't know what, if anything, can be done by htmerge
to prevent this.

Now this is a problem.  I guess it's not critical if it only happens
when the word database is completely empty, but htfuzzy should be
robust enough to handle this without crashing.
