Error when using pudb with ipython

Question

I'm trying to use PuDB with ipython as the shell, but when I drop to shell, I get the following error:

can't set attribute
Error in atexit._run_exitfuncs:

Answer 1

This is a known issue, and should be fixed in IPython 0.12.1 or master. Does updating to current (0.12.1) IPython help?
