Ok, I'm done.

    if changed buffer is not shown in a window.
    * insdel.c (prepare_to_modify_buffer): Likewise.
    * window.c (replace_buffer_in_windows_safely): Do nothing
    if buffer is not shown in a window.

    is passed.

In bzr, that's revno 111189.

BTW: I first tried the bzr bisect plugin, but I got frequent conflicts
in cl-loaddefs.el when it switched to another revision.  I used "bzr
resolve --take-other lisp/emacs-lisp/cl-loaddefs.el", and in the end the
bisection aborted somehow.  I also had lots of problems with files that
were added/removed between revisions.  Are there any instructions on
doing bisection on emacs bzr?  Maybe I've just operated bzr bisect
wrongly...

Anyway, git bisect on the git mirror worked flawlessly.

Bye,
Tassilo
