I only see this outside a virtualenv, haven't investigated the root cause yet, but at the very least this should be a warning a a fatal crash and burn.

Even the python stacktrace couldn't get the source code, and it looks like you might be doing something fancy with compiled python or a ZipImporter? I agree, we should wrap the getsource functions with a try-except. I can take this one if you haven't started it

[grybmadsci]

I don't think we were doing anything fancy, just running on an ubuntu install, but outside a virtualenv.

Outside a virtualenv, meaning using the default system python?

[grybmadsci]

Yep, default system python on Ubuntu.
