memory leak

Hello,

I have some python code in a pyobjc app. At some point I want to initialize a NSString :

	string = NSString.alloc().init()

In the terminal I get the following output :

/Users/dlsa/code/cirrusstore/client/build/cirrusclient.app/Contents/Resources/menubaractions.py:44: UninitializedDeallocWarning: leaking an uninitialized object of type NSPlaceholderString
  string = NSString.alloc().init()


I have in my objective C bootstrap code the creation of an Auto release pool.

If I try :

	string = NSString.alloc().init().autorelease()

I get the same warning.

Why does this happen ?
