I don't think this is true?

1) bridge lines in your torrc do not say a DirPort, so how would the
client accidentally try to use it?

2) We don't let bridges open a DirPort, as of Tor 0.2.2.x:
https://gitweb.torproject.org/tor.git/tree/ChangeLog?id=tor-0.2.7.6#n9744

3) Bridges should refuse to serve their descriptor except over a begindir
connection on their ORPort:
https://gitweb.torproject.org/tor.git/tree/src/or/dirserv.c?id=tor-0.2.7.6#n3477

So I hope it is hard to run into this edge case. :)
