In _TestZZZNumberOfObjects in test_multiprocessing.py, at around line 1040  
(this is r65075 on the trunk), there's a line:

            print self.manager._debugInfo()

Should this be

            print self.manager._debug_info()

?

While running test_multiprocessing directly (./python.exe 
Lib/test/test_multiprocessing) I got the following traceback:
