Thanks.  Unfortunately, I seem to be unable to reproduce this with the
Emacs configurations to which I have access.  One thing I couldn't try
was a GUI session that also has a TTY frame created by "emacsclient -t",
I could only try a TTY session in which another TTY frame on a
different terminal was created by emacsclient.  Maybe this is the
crucial difference: do you see the same problem when Emacs that runs
the server is started with -nw?

Did this problem appear lately, or do you see it in previous versions
as well (e.g., on the emacs-24 branch)?  If this only appeared
recently, could you perhaps bisect to find the commit which caused
this?

Also, would you be ready to run Emacs under a debugger and look around
where I suggest you to?

Thanks.
