[Pyobjc-dev] import QTKit -> NSRecursiveLock errors

[Daniel A. <an...@cc...>]

I think I remember there being some discussion of this a while back,  
but couldn't find it.

Try this:
1) Make a new Python Cocoa app in Xcode
2) In the application delegate, insert the line "import QTKit"
3) Run it

I get:

_RegisterApplication(), FAILED TO establish the default connection to  
the WindowServer, _CGSDefaultConnection() is NULL.

This is particularly frustrating as, in my real project, I am trying  
to make a subclass of QTKit.QTCaptureView; however, I can't, as  
importing yields the above errors.
