I can remember having a conversation with Christian Costa for the same kind of error. 

That was after he added some extra filter registration in quartz/regsvr.c. I just played
around with the CoInitialize in register_filters.
I changed CoInitialize(NULL) into CoInitializeEx(NULL,
COINIT_MULTITHREADED) and the error was gone.

When I do the same change now, the X Error is gone as well. Does this
give you a clue?
