Wow, this is weird.  It's producing color escapes for the prompts,
which I don't see here and have no idea how they are happening,
because I'm initializing the internal instance in nocolor mode.  Very
bizarre.

Could you do me a favor? Try the attached patch and see if that helps,
I'm a bit stumped.

same error as above

Huh? That doesn't make any sense.

Are you sure you're running off the branch?  I don't use 'setup.py
develop', so I'm not sure it works correctly.  I simply have in my
PYTHONPATH a symlink to my source ipython directory, so that

import IPython

loads the right version.  Could you verify that you are getting the
right version?

Same again as before..

The config system is different now:

There is no way to know this in python in general, since multiple
names can be bound to one object, assignments can happen in many
different ways (code can write to namespace dicts directly, etc).  But
you can write a little extension of yours that walks the In input
history list looking for things that look like variable assignments.
It won't be very robust, but could be useful.  If you end up liking
it, put it up on the cookbook and we can ship it later as an optional
tool, once you've stress-tested it.

Cheers,
