C-g crash in C-x C-f (OSX Lion)

[Carsten Mattner]

As previously mentioned Emacs.app reliably crashes for me
on Lion in trunk builds.

Crash happens if I was waiting in C-x C-f and at some point
later after having switched away and back to Emacs.app
decide to cancel the the file open by pressing C-g.

This time around I saved the OS-provided stacktrace.

Is this of any use to track down the source?
