Unable to generate debug file

I upgraded to 12.0-RELEASE and am having several major issues. In the process trying to report them I have also found that I cannot generate a debug file. I believe it breaks at 72%. The initial error is ```Error: [object Object]```

Followed a minute or so later by ```Error: Traceback (most recent call last):
