Okay, please try out the latest commit (136), which should have fixed this problem.
The issue is that some Intel drivers don't do mipmapping properly and Clutter's font-cache ends up being non-existent. Forcibly disabling mipmapping before the fonts are created should fix this.
Testing appreciated, I've left the bug open until we have some confirmed fixes.
