I have no idea. Apparently the difference between the afm files is:

45c45
< C 27 ; WX 1000 ; N ZdZ2708 ; B 41 322 956 25886 ;

< C -1 ; WX 1000 ; N .notdef ; B 0 0 0 0 ;
---
> C -1 ; WX 1000 ; N .notdef ; B 225 68 315 685 ;

and most probably it does not like the value of 25886. Maybe
the Freetype people can say how it gets there.
