bug#12310: crash in remember_mouse_glyph

[Werner LEMBERG]

[rev 109796]

This crash, which happens rather frequently, is something introduced
quite recently.  My last bzr build (in June, IIRC), using the same
GNU/Linux environment (gcc 4.6.2, KDE 4.8, Qt 4.8), didn't show this.

It seems that the crash happens if I look at e-mails with CJK
characters (using Mew), then composing a simple e-mail, then trying to
send the e-mail.  I have no exact recipe to reproduce, sorry.

I still have the emacs process in gdb, so please advise how to
proceed.
