Not sure what Emacs can do under these conditions.  However, it worked

Dmitry, this is bzr revision 113891.  Perhaps the new code in
delete_frame should include a few more tests from candidate_frame?
(That's just a wild guess, though: I don't really understand what does
tmux do to Emacs -- are we selecting a frame that is no longer
displayed or something?)
