I keep seeing this in Insiders when trying to set a BP.

@roblourens I can not reproduce this - how do you set the breakpoint, in what type of file?
This minimized stack trace is not a lot of use to me - you could open developer tools > pause on exceptions > format minimized code and send the screenshot on where you break.

Also you could try reproudcing with out of source

In Javascript, usually after a couple debugging sessions in the editor. Goes away for awhile if I restart it.
