Hi,
this happened couple times today in the particular document, which loads ton of
pdf images,
somewhere in the middle of initial loading and scrolling (at the same time).
I'll try to come up with some recipe, but it seems very hard to reproduce on
demand,
I need to load it like 20x to get it again with some lucky random scrolling
pattern.
Combination of page up/downs seems to be enough to triggers this. And cache
needs to be clean before running so the convertor mechanisms take time to load.
Thanks for the backtrace. So is it only a thing in branch? Note that the
assertion in ParagraphMetrics::position() is new, so this might be an
old problem that we detect only now.

I can probably produce some lyxerr output if particular position params would
be of help.
