Cannot unmarshal non-string into Go value of type common.Address

[rhyeal]

When I run the example.yml file as such:

deploy-contracts --deployment-file=crowdsales/example.yml --deployment-name=ropsten --address=0x123456sample

I receive back the following error stack and the contract is not deployed:

Owner address is 0x123456sample
Owner balance is 4.9749654176 ETH
Already deployed contract, team_multisig 0x40a05d4ce308bf600cb275d7a3e9113518f59c54

It seems that line 66 of the ico/deploy.py file, specifically the first JSON object deploy_transaction is parsing the from value as a non-string, despite a single quote, double quote, or no quote hard coded value being put in there. Obviously I can't deploy any contracts as a result to further test the code I'm writing, so this is a blocker for me using the ico package.

Any thoughts on what's causing the issue?
