Comment 8 for bug 901541

I can reproduce the error also with argparse.py of Python 2.7.2, and with python-mode 6.0.3. After opening the file, hit several C-v's until the cursor enters in a class, then hit TAB. Then the error occurs.
The exact position was not the point; in also #7, I used only C-v and <down> to move cursor. If I use C-u C-M-e to move to the end of the class, the error does not occur.
