Impossible to execute coupon code in cart or checkout when having more then one different products in the shopping cart.

Reproduce:

1. make an auto generated coupon code that does a discount for the whole cart. Condition is that the subtotal minimum of x is met.
2. one single products to the cart and apply the coupon code --> this works just fine
3. now add a different product to the cart (the two products must be different sku)
4. apply the coupon code (iin the cart or the checkout; doesn't matter)
5. result: {"messages":{"error":[{"code":500,"message":"Server internal error. See details in report api/571656540374" }]}}

@SidneyBilliet Thank you for reporting the issue.
I could not reproduce the error you described on the latest commit, could you please check if there are any additional conditions and provide the generated error report?

Can you show the contents of the var/report/571656540374 file?
If it is not possible, please enable developer mode (uncomment "SetEnv MAGE_MODE developer" in root .htaccess) and run your test again -- you will be able to see the stack trace.
