That's not a filesystem representation (code for "UTF-8 encoded path").

When CF stuff crashes, you can often get more information by using the
debug version of frameworks:
% DYLD_IMAGE_SUFFIX="_debug" ipython

It's hard to say if the crash is Python's fault or CF's fault, but
there's definitely a wrapper bug in there. And it looks like you need
the trailing slash; didn't bother to check if that is by design or
not.
