Do you use Anti Aliasing font and embedded bitmap font having truetype
font ? 

If you use Anti Aliasing font and embedded bitmap font having truetype
font, I think that freetype causes this problem. Because, I had this problem 
(completely freeze) previously. And when I applied the attached a patch and
did recompiling of freetype and reinstall of freetype, this problem was 
solved.

I think that the handling of embedded bitmap font in truetype font with
freetype was a problem.

I hope this help solves your problem.

PS: I use XFree86 4.2.0 and Freetype CVS STABLE version.
     Current stable version is 2.0.9.
