Oooh, I'd rather not dig into the C code, scary... :) However, if it
will help solve this problem I might give it a shot.

Don't look at me, it's not me who generates those messages :)

A lot of text, yes...

Agree.

Yes, this is strange... And even more strange is that the recipe
[(x-focus-frame (selected-frame))] that generated the problem
yesterday does not work today... And when I think of it I haven't got
any single problem today... I hate this...

If you mean "emacs - ma" above, yes. "ma" is a truncated Emacs buffer
name. In other tests there have been names such as ".emacs" or other
buffers that was visible at the time.
