 '''__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

 '''__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.
