I can very well reproduce this bug, I don't even need
to do Document -> Page -> Type -> Paper, nor to remove
the .TeXmacs.

I just open the document, then scroll down with the
mouse, and then it crashes. The strange thing is that
if I move the cursor down with the down arrow, and
then Go back to the top of the document as it was
in the first place, scrolling down with the mouse
doesn't crashes anymore.

Probably a bad initialization of the variables in
the C++, but which one ? This problem is also likely
to be related to the kind of markup you use, I would
say.

See this in some time.

It would be great, this way we are sure it will not be forgotten.
