Hi all,
yesterday i got multiple instances of phonon playing on the same main thread without problems, but if this happen on differents threads, its simply crash:

X Error: BadDrawable (invalid Pixmap or Window parameter) 9
Extension: 140 (Uknown extension)
Minor opcode: 9 (Unknown request)
Resource id: 0x3400590

What do i need to get it working properly?
protect X11 from concurrent rendering?

** Im using phonon-4.2 with gstreamer backend.

thanks in advance,
Rafael Savignon.
