Comment 12 for bug 1210775

Hello,

I just encountered the same problem.
At my local Magento 1.7.0.2 instance everything is working fine and "customer.info" returns a bunch of values.
But on another Magento instance (also 1.7.0.2) the call only returns " {'customer_id': '7', 'updated_at': '2013-10-10 11:30:34', 'increment_id': None}"

It seems that the magento installations are not equal, but I do not find out where the difference is ...

I also found out that removing the param "None" would resolve the problem, but this can not be the final solution.
The problem also occurs with other objects like "catalog_category".

Any suggestions are welcome
