Comment 2 for bug 1519859

Ok sorry it took me so long to reproduce this, but I finally figured out when the bug occurs. Consider the following script:

def main():
    print 'this is a test'
    print 'this is another test'

if __name__ == '__main__':
    main()

Executing this script will work as expected. If both the print statements are highlighted using the mark (or manually selecting line 2 and 3, and then invoking M-x py-execute-region I get the following error:

indent-rigidly-left: Symbol's function definition is void: indent-rigidly--pop-undo

Note that if the print statements are on their own (outside a function declaration, the py-execute-region works as expected, as well as any indented code.
The thing that causes it to break if it's wrapped in a function, in this case the main()

Can you reproduce?
