 Thanks for catching that bug. It turns out that we also need a small patch
 to Torbutton:
 https://gitweb.torproject.org/user/brade/torbutton.git/commit/?h=bug29430-01&id=844693481ce92bb34536113a318211cbaedde4bd

 This will fix the immediate problem. In the long run, the control port
 response parser and circuit display code should be more robust and not
 completely fail when it sees a bridge type that it does not recognize.
