Discounts/Cart summary ContextErrorException

[LazyCircles]

Hello community, 

I'm configuring some types of discounts on our store and found a weird bug related with the cart summary (it is not theme related because I changed to the default one and the error still appears).

So, I was configuring a simple buy 2 get 3 products but when I try add the third product, the ajax add to cart goes infinite loading and the page after 30 seconds +/- gives a HTTP ERROR 431 (in chrome), blank page (Firefox).

After this I've enabled debug mode to check where the problem is and got this:

 (1/1) ContextErrorException

This alert appears everytime I go to the cart summary with or without the discount active. 

I've commented the content of cart-detailed-totals.tpl and the error doens't show up but I don't think that's the way to solve this problem.  

I'll leave the discount configuration in the attachments. 

Let me know if I wasn't clear enough. 

Thank you for your attention,

KR,
