It's a bug in the copy of PyObjC that's included in OSX 10.6:

$ /usr/bin/python
Python 2.6.1 (r261:67515, Jun 24 2010, 21:47:49) 
[GCC 4.2.1 (Apple Inc. build 5646)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
:>>> from Foundation import NSString
:>>> NSString.alloc().init()
__main__:1: UninitializedDeallocWarning: leaking an uninitialized object of type NSPlaceholderString
u''
:>>> s = _
:>>> type(s)
<type 'objc.pyobjc_unicode'>
:>>> 

I haven't researched yet why this happens, and later versions work properly.
