23.0.50; Face `modeline' unexpected change

[Leo]

Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the address@hidden mailing list.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

To reproduce:

In xterm, use `emacsclient -t' to connect to emacs server and then in
urxvt also use 'emacsclient -t' to connect to emacs server. Now go back
to xterm and the face of the modeline has changed to some funny
color. See:
