I think the bug happens because we use save-window-excursion, and
switch buffers inside it.  The cure should be not to do what hurts.
Can this be done in this case?  If not, why not?  And why do we use
save-window-excursion in the first place? that's not the usual way to
display a buffer whose contents is referenced in an error message or a
prompt.

Thanks.
