bug#8552: Error with multiple frames |

Package: Emacs,Gnus
Version: 24.0.50
I use the following patch which doesn't do quite the right thing
I think, but at least doesn't burp in my use. The problem is of course
that get-buffer-window may return nil rather than a window.
I've bumped into it when I select a group, then select an article in the
summary, then do C-x 5 b *Group* and then from the summary buffer hit
`q'. Sadly, this recipe doesn't reproduce the problem, and I'm not sure
exactly what sequence of actions reproduces it, other than the fact that
it happens when I leave a summary buffer and the *Group* buffer is
already displayed in some other frame. If/when I bump into it again,
I'll send you the corresponding backtrace.
