Thanks.  Nice but not amusing.  Things like that never can happen.  So
presumably *Server* is the buffer you want to get rid off.  I can only
add another diff based on that assumption.  Please put a breakpoint on
that non-sensical

                  best_window = Qt;

line 3050 in window.c.  When it triggers please use "s" to painfully
step through the entire set_window_buffer and other_buffer_safely below
and tell me whether you find something fishy: Is other_buffer_safely
called at all and what is the name of the "buf" it returns?  Does
set_window_buffer for some reason refuse to wset_buffer to the one
returned by other_buffer_safely?
