Comment:

 The branch `bug18162_024` in my public repository has a proposed fix for
 this bug, along with a small family of related bugs.   You can see the
 patch here:
 https://gitweb.torproject.org/nickm/tor.git/commit/?h=bug18162_024&id=bca7083e8285e8e6a4377076a7e432417eafc6d2

 Review would be much appreciated.

 From an abundance of caution, I've written the fix to apply to 0.2.4 and
 later, though I doubt that's necessary.
