The googlegroup has search options, here's what I get if I search for
OpenMW. it comes up with several threads with you contributing:

I had to step back from the OSG support side as it consumes so much time
and mind-share, it's not really possible to tackle other complex work at
the same time so I'm having to block the OSG support side and not tackle
any complex other work during this period. I don't disappear completely, I
just step back.

Anyway, on to the matter at hand, I don't get the crash, but I'm missing

If you have things you feel would be suitable to merge with the 3.6 branch
please make them. I can't review and provide feedback.  To properly judge
changes I do need to understand the motivation behind them, it may be that
the changes are workaround issues that are based solved in other ways.

When you say not seeing the crash, I we talking about a different issue to
what Fabian was referring to?  Is Fabian working on the same versions of
OpenME and OSG as yourself?

I guess that means that I've not really given any more information beyond

The OSG falls back to using the DefaultFont when the requested font can't
be found, so any chance this might be happening?  Something like font files
missing, case of the font being different - Windows isn't case sensitive so
when you move to a case sensitive OS you can see issues if there are errors
in the filename.
