Ok, I poked some more at this, and it seems to be a problem with 
FcNameRegisterObjectTypes() and/ or FcNameGetObjectType(). What is
happening is that Xft calls FcNameRegisterObjectTypes() to register some
additional names, "render" being the third one. There seems to be some
confusion wrt to the assignment of ids to the registered strings, at
least we end up with "render" from the Xft strings getting id 2, which 
is the same id as "style" from the FC registered strings got. This has
then the effect that setting "render" to TRUE sets "style" instead,
which is bad, since "style" is not a boolean...
