I just updated this to r.02 alpha, and I know the PTS doesn't support addons this week.
The intent of BugCatcher is to give developers and users more control of how they want their errors displayed. It hooks Event.System.Error, so it catches all errors, addon or Rift itself.
You can read the full (it's short!) description

Any feedback is welcome, whether to discuss BugCatcher's code, suggestions, or general usage. Please post in the addon comments.
