Thanks for investigating this and sorry for the false alarm.

Turns out I had Drew Adams' "frame-cmds.el" in my load path, which
contains its own version of delete-windows-on and which somehow was
being loaded even for "emacs -Q".

Right... It turns out that version from frame-cmds.el doesn't handle
the case of "buffer" argument being nil all that well... Drew, you
might want to do something about that :)
