I hacked my by removing the this.add_events code, so it doesn’t do it anymore.  I think you are right about it being load time related.

		Hi guys
I think I’ve figured out the issue but will need to test further.
This error seems to occur when the main editor tab is set to ‘text’.
If you set the tab to ‘visual’ and reload the page, there is no JS error.
I’ll start digging through code to figure out why and have this fixed shortly!
Cheers
E
