[IPython-dev] pdb errors on latest checkout

[Matthew Brett]

Hi,

As of about 4 days ago, I have been getting errors whenever I try and
enter pdb, with the latest bzr checkout:

blair:~ mb312$ ipython
Python 2.6.4 (r264:75706, Nov 29 2009, 00:03:57)
Type "copyright", "credits" or "license" for more information.

IPython 0.11.bzr.r1205 -- An enhanced Interactive Python.
?         -> Introduction and overview of IPython's features.
%quickref -> Quick reference.
help      -> Python's own help system.
object?   -> Details about 'object'. ?object also works, ?? prints more.

I'm afraid I got a little lost trying to debug this - is there
anything obvious I should try?

Thanks a lot,
