Description of problem:

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
Traceback (most recent call last):
  File "/usr/lib64/python2.6/runpy.py", line 122, in _run_module_as_main

    return os.path.basename(sys.argv[0])
IndexError: list index out of range

Version-Release number of selected component (if applicable):
python-2.6.6-52.el6.x86_64

How reproducible:
always


In addition to this the list of possible sort values is not available and one needs to dig into the code to figure it out.
