When I try to compose an email, either directly or by pressing 'm' in
Gnus, I get the message:

`recenter'ing a window that does not display current-buffer.

This is using Emacs built from source on June 9th 2014, running on Mac
OSX 10.9.3. The message appears to come from a change to add additional
validation to src/window.c on June 6th with SHA:
