New submission from Julian Berman <Julian+PyPy at GrayVines.com>:

Python 2.7.3 (5acfe049a5b0, May 21 2013, 13:47:22)
[PyPy 2.0.2 with GCC 4.2.1 Compatible Apple LLVM 4.2 (clang-425.0.28)]

Getting the following traceback with a curses app (bpython):

⊙  bpython -i wsgi.py

Don't have time to investigate further at this exact moment, so apologies, but the 
quickest way to reproduce is:

$ mktmpenv --python=pypy
$ pip install bpython flask
$ bpython
>>> import flask
>>> flask.Flask

and then hit (, which will trigger bpython's tooltip for docstrings and along with 
it that traceback.

If I get some time to dig I'll update with more details, though I bet this means 
enough to let you guys know what's up already if you're familiar with the curses 
integration code.
