Comment:

 Okay, I'm pretty well stymied.  I'm not sure where this RS is coming from,
 or how it's getting in this state. I think my best bet for now is to write
 a diagnostic patch to disable the assertion here, and instead log what we
 can find out about the routerstatus.

 Branch is: diagnose_32868_035
 0.3.5 PR: https://github.com/torproject/tor/pull/1661
 master PR: (for CI) https://github.com/torproject/tor/pull/1662

 This won't fix the underlying problem, but I think we should consider
 merging it to help track the problem down.
