Tests pass fine.

I seem to have fixed it, I found an old thread where someone mentioned
#hash, so I looked and I was using a custom biz object as a key into a
dictionary.  I think I was a bit careless with overriding #= and #hash and
had maybe done something wrong.  I changed the key to a string instead of a
custom object and the error seems to have gone away.  Haven't had an error
in the last hour and a half since pushing this out.

I did actually have this error in 2.7 as well but it was so rare I'd never
bothered with it.  Not sure why 2.8 made it happen at a much higher
frequency, but I don't think it was a Seaside problem now.
