I believed it too but I was too focused on the issues of
with-silent-modifications and thus the 24.3.50 tag. Now I cannot
reproduce the problem on 24.3.50 any more.

I might have some missteps in the initial report. I discovered the
problem while running 24.3 on my laptop then ssh'd to a centos 6 server
where there is daily build of emacs and "saw" the same issue there.
