bug#23856: 25.0.95; Crash on cancel print dialogue

["Alf Lervåg" <alf@lervag.net>]

Occasionally I press cmd-p by mistake. When I press cancel in the print dialogue, emacs crashes. This is annoying. Let me know if there is anything I can do to help locate the root cause.

1. Press Cmd-P
2. Press Esc
