[Ipe-discuss] IpePresenter not showing LaTeX rendered results

Wow, that was a fast reaction. Thanks.

However, now I have weird behaviour. One of two things happens (not sure
when which happens) when I start ipepresenter:

1.) It segfaults somewhere in font::getShape (I'm not currently able to
reproduce this, currently only 2 happens:)
2.) In two of the three canvases, all letters (i.e. all glyphs rendered
by Latex) are replaced by boxes

I assume there is some race condition now. I'm sorry, I'm not really
familiar with the codebase and I'm trying to patch this together (got a
presentation tomorrow...) - is there anything that must necessarily
complete before the values from doc->resources() are initialized?
Currently, doc->recources() is called more or less right after
Document::loadWithErrorReport().

Thanks again,

Lukas
