Predrag, considering the last comment in the Mozilla bug above (claiming 
the bug went away when updating fontconfig), would you care applying 
patches [1] newer than 2.13.1 release on top of userland fontconfig 
component, build it and testing? At lease some of them look to be 
related to your problem.
