I've forgotten to add the sort value to the -s option of cProfile which results in a traceback instead of user friendly error message. In the example below hello.py just prints a "Hello World":
$ python -m cProfile -s hello.py

Tested with python2.7, python3.4 with the same result.
Attached patch adds `choices` for sort option of cProfile.
