I have solved the crash. I have been using it for the thirty minutes and  
no crash so far. If I do unpatch and it will crash within five minutes.  
Here's patch to put in freetype2/files. Don't know if patch is right, but  
at least it's fixed for me.

I found it by compared freetype2 2.1.9 and 2.1.10, you can check if you  
want to see for youself. I removed compare of Makefile, configure and  
other useless stuff.

It looks like 2.1.10 removed or disabled *find_sbit_image? Search for  
'find_sbit_image' in freetype2-compare.diff.bz2.

Cheers,
