Did you make any progress with this? Please share anything you deem useful here, you might just help someone out.
Assuming you have a test environment, your first check should be - can you duplicate the behaviour in your test environment?
If so - the first piece of advice would be to upgrade your test environment (Core and Client) to SP3 (since SP1 is ... 2 years old, if not more?) and see if that helps you?
