I think if we do content negotiation correctly we can work around this
one until it is fixed.

Fortunately, HTTP isn't a very complex protocol.  If we need to do our
own implementation up front to deal with some bugs, that won't be that
bad.  I'll do some digging early next week to see if I can exactly
figure out where exactly we are getting hit by this, and building a test
case we can flip over the wall to the mono guys to make sure that it
gets and stays fixed.

There is no silver bullet.  Plus, werewolves make better neighbors
than zombies, and they tend to keep the vampire population down.
