Crash from Gtk when running with remote display

[Kai Grossjohann]

This bug report will be sent to the Free Software Foundation,
not to your local site managers!
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:

I have a laptop (running Debian GNU/Linux unstable).  Running this
version of Emacs on it works well, but for some time now I've seen
crashes when running remotely with X11 redirection.

I log into my FreeBSD -current box, starting X11.  Then I log in via
ssh to my laptop, redirecting the X11 display to the FreeBSD box.
Then I start Emacs.  But it crashes when invoking the menu.

I have captured a session where I invoked Emacs (with "-q
-no-site-file"), then clicked on the Help menu item.  I'm not sure
what else to look for.  Also, I'm not sure whether and how this can be
reproduced without Debian GNU/Linux and FreeBSD.

Please let me know what I can do to debug.

(I should also note that I'm using the Debian packaging from
http://people.debian.org/~jerome/.)
