Message2675

Attempting to pass a None globals object to __import__ raises an error.

This is commonly done when you only want to specify one of the last arguments (like fromlist), and don't bother specifying globals (or locals), e.g.:

__import__('mypackage.mymodule', None, None, ['mymodule'])

Tests are also attached. Without the fix, the following is raised by the new test:
