I'll try it later. While I played with the problem a bit more
yesterday I narrowed it to the following action.
(overlay-put
(make-overlay (point-max) (point-max))
'before-string
"[End of message]")
The difficulty to reproduce this for you is that it is buffer content
dependent. If I save the buffer to a file the text properties are
gone. I don't know if text properties are relevant to this problem
but saving the buffer to a file and revisiting it and performing above
action does not produce the problem anymore. Is there a way to save
the complete buffer information to a file including text properties?

I agree with your insight.
