I also get the atexit KeyErrors when I use IPython's Pdb subclass outside of 
IPython. There should probably be a guard there in case the output cache has not 
been set up. Similarly with the other KeyError.

As for the first AttributeError, the interface changed very recently. You no 
longer provide a user_global_ns dictionary. Instead, you provide user_module. 
user_global_ns is a read-only property that gets the dictionary from 
user_module. IIRC, this was done to help with the perennial problems we have had 
with faking the __main__ module.
