This isnt a bug.

The error is coming from SecureActionButtonTemplate and its its error because you are creating an invalid state. Once you create a frame it cannot be destroyed (WoW limitation). The fix is to change your sequence to macro blocks or pick one talent set and spec for the character and never change. This is a limitation of this particular mode. It also cant do any AoE abilities.
