I don't see this problem on MS-Windows: the frame name is not
displayed in the mode line, and the value of
mode-line-frame-identification is "  ", as I'd expect.

I won't have access to a system with X for a couple of days.  If you
still see this with the current CVS, please put a breakpoint in
decode_mode_spec and tell me when and from where it is called ``at the
wrong time''.
