Control Protocol Spec Error, Grammars Use Outdated Production ServiceID
Problem
The grammar for circuit-status (https://gitweb.torproject.org/tor.git/blob/HEAD:/doc/spec/control-spec.txt#l473) is not correct. Note that the grammar of Path (https://gitweb.torproject.org/tor.git/blob/HEAD:/doc/spec/control-spec.txt#l1003) specifies a list of ServerIDs (https://gitweb.torproject.org/tor.git/blob/HEAD:/doc/spec/control-spec.txt#l100), which are either a Nickname (https://gitweb.torproject.org/tor.git/blob/HEAD:/doc/spec/control-spec.txt#l102) or Fingerprint (https://gitweb.torproject.org/tor.git/blob/HEAD:/doc/spec/control-spec.txt#l104). However, as you can see below, I got a list of LongNames (https://gitweb.torproject.org/tor.git/blob/HEAD:/doc/spec/control-spec.txt#l124) instead.
How to Reproduce
Start Tor with open control port
mil:~ tim$ tor --ControlPort 9051
Nov 15 !8 (merged):27:11.110 [notice] Tor v0.2.2.17-alpha (git-dadd9608)

How To Fix
To fix this specific problem the grammer of circuit-status or Path needs to be updated. I haven't explored the specification in depth to see what effect this will have in other areas.
