are you still having this problem? Looks like a fontconfig problem, not TeXmacs, so  this is not likely not help, but you can try running "texmacs --setup" to rebuild the font cache.

I am running version 1.99.2 on Fedora 21. It pretty much crashes all the time. It is hard to say exactly what causes it, but usually after or during File->Export->PDF. As far as I can tell I have the latest version. Is there a work around for this bug? For now I just make sure I save all my files before trying to export anything as PDF. Thanks for any help.

Here is what I get on the terminal from start up to crash:
