This not the correct syntax; Ligatures=TeX is a fontspec option and
should be passed to it: \setmainfont[Ligatures=TeX]{Gentium}. What is
inside the curly bracket is passed to XeTeX as font name, so it should
be just the font name (or file name, fontspec knows how to handle
this).

I'll try to see what is going on here, might be a bug or just XeTeX
trying hard to find the font from the incorrect name it is given.
