[IPython-dev] using class instances with ipython1

Is it possible to use class instances with ipython1?  I'm getting an
import error message whenever I try to pass a list of class instances
to engines. I've attached a test script and a module, testclass.py,
with a simple, pickleable class defined in it. Here's the traceback:

mmclay@mmclay:~/src/scratchpad$ python test_ipython.py
[<class C 0>, <class C 1>, <class C 2>, <class C 3>, <class C 4>,
<class C 5>, <class C 6>, <class C 7>, <class C 8>, <class C 9>]
Traceback (most recent call last):
