How to restore object repository after adding a new project type when getting "Invalid image size" error?

Question

I was playing around with adding a new project type to the object repository. I've added an icon and a description, but nothing else and now I can no longer do a File|New|Other, which really makes working with Delphi difficult.

I can get to the Customize menu (File|New|Customize) and I can see what I "added" and the icon is there with its description:

But when I try to go to File|New|Other, I get the Invalid image size error:

and I can't seem to figure out how to undo what I did. Clicking on Details button yields the following:

Answer 1

Two ways roll this back:

1) delete the RADStudioRepository.xml file that resides in \AppData\Roaming\Embarcadero\BDS\12.0. Delphi recreates a default file when restarted

2) edit the RADStudioRepository.xml file to remove the offending entries.
