load fails with AssertionError: "assert '\\' not in type_str"

At least for my case, removing the assertions seems to have done the trick, but I haven't looked through the code enough to know if there's actually a valid reason for them being there.

Can you post the actual traceback?

Gary told me offline he couldn't reproduce this. It might have been implicitly fixed by me changing our build to use simplejson.

I can confirm that this is a problem I'm currently experiencing. Commenting out the assertions, though, does allow me to work around the problem.
