ipython emacs IndentationError

Really annoying problem in ipython prompt in emacs:

In [128]: if 1==1:
   .....: print "yes"
   .....: else:
   .....: print "no"
   .....:
IndentationError: unindent does not match any outer indentation level

It looks perfectly aligned to me, not sure what trigger the error. No such problem when I do this in terminal.

A solution is given at the very place:

You might try toggling autoindent with

%autoindent

since I think that has caused the problem for me before.

You can change this permanently using ipython's customization. After the proper imports (see the link) the following should work in ipy_user_conf.py:

# Emacs sets the term to dumb so we can distinguish that way
if os.environ['TERM'] == 'dumb':
    ip.options.autoindent = 0

Remains the question how to deal with this from python-mode.el
