It's okay now, I was able to piece it together.

@Louis
Did you get the trial to work? If so, how?

Problem is most likely this:
> 0114:fixme:commdlg:pagesetup_update_papersize No papernames found for L""/L""

Later on we have
> pagesetup_get_papersize_pt(data)->x = tenths_mm_to_size(data, points[i].x);

If we abort (see that fixme), the x/y values are never initialized and we get a
divide by zero.
