Your version of GTK+ will have problems with closing open
displays. This is no problem if you just use one display, but
if you use more than one and close one of them Emacs may crash.
See <https://bugzilla.gnome.org/show_bug.cgi?id=85715>.
If you intend to use more than one display, then it is strongly
recommended that you compile Emacs with the Athena/Lucid or the
Motif toolkit instead.
