bug#24614: 25.1.50; Exception after moving mouse over over a different w


From: Alain Schneble
Subject: bug#24614: 25.1.50; Exception after moving mouse over over a different window
Date: Tue, 4 Oct 2016 16:53:14 +0200

I was working in an emacs-lisp-mode buffer displayed in a window of a
frame divided into 4 windows.  After moving the mouse over another
window showing an org-mode buffer, Emacs crashed.

Below is the backtrace.

Thanks,
Alain
