[SalesForce] Lightning Tab with Lightning Component throwing error (but the same component loads fine with App Preview, on SF1 & VF Page lightning out)

We have a lightning component, which is being used in VF page Lightning out, SF1, App Preview & Lightning Tab in Lightning experience. Until Summer'16 it is working fine. Now it doesn't load in lightning experience, but loads fine in others.

The below is the error it throws when we are trying to load the lightning tab in lightning experience.

This page has an error. You might just need to refresh it. First, would you give us some details? (We're reporting this as error ID: 47a0514c-2363-44c2-8730-32e6f570915c)
