Why do I get a module has no attribute __main__ in ipython parallel gather statement?

Question

This is a related question to this one:

The difference is that now I'm trying to use_dill in ipython parallel and when I try to pull data it gives me an error. I have no idea if the data is ever pushed.

dv['a'] = 1
dv['a'] # <- this gives an error

The error I get is:

*** CompositeError: one or more exceptions from call to method: _pull
[0:apply]: AttributeError: 'module' object has no attribute '__main__'
[1:apply]: AttributeError: 'module' object has no attribute '__main__'
[2:apply]: AttributeError: 'module' object has no attribute '__main__'
[3:apply]: AttributeError: 'module' object has no attribute '__main__'
.... 9 more exceptions ...

I have no idea what is going on, any help is much appreciated.

If you want more info please let me know and I'll add it.

Thank you
