Thanks for the report.  Would the attached patch fix it?

BTW, I notice that you quite often run functions with a current buffer
different from that of the selected window.  In all these cases
`quit-window' might misbehave for you because it does not restore the
buffer that was current at the time the window's buffer was displayed.
So if you see any problems in this context, please tell me.  We then
could try to restore the current buffer (optionally at least) too.
