test_cfstring (Cocoa bindings) fails on OSX 10.7 with Python 3.2 and 3.3 on x86_64.
This is because CFStringTrim fails to work (trims at front of string, not at end). The reason for this is not clear. Trimming works fine when the second argument is a "real" NSString, not when it is a OC_PythonUnicode object (e.g. a proxies python unicode object).
The tests pass in 32-bit mode and using python 2.7 (with a unicode string).
This shouldn't affect most users, but is cause for worry anyway
