Bleh. I'm guessing your circuit build times data is somehow
degenerate/corrupted. Perhaps you ran out of disk space and the state
file got truncated?

If you can reproduce the issue reliably, can you perhaps send us the
results of something like 'grep "Build" /var/lib/tor/state'? Private
email is fine.

Don't ever publish the entire state file though: it is dangerous to your
hidden services' anonymity.
