bug#14092: 24.3; crash in remember_mouse_glyph

[Steve Vinoski]

Not sure what exactly triggers it, but I've been seeing this on various
builds of emacs 24 since last august or september. This time I was
simply opening a file in a new frame and then mousing over to start
entering text into the file. Here's the traceback from the Apple crash
report:
