I cannot reproduce this.  Please provide a more detailed recipe,
starting from "emacs -Q".

The error was with 'emacs -Q'.

1. Start emacs with: 'emacs -Q test.py'
2. Type 'a = ['
3. Hit enter

What happens: See "Wrong type argument: number-or-marker-p, nil" at
the bottom of the screen and the cursor on line 2 at column 0.
What I expected: No errors, and cursor on line 2 at column 4.

Thanks, this is already fixed in the current development version.
