Broken install profile results in non-working site, but no errors during site Install or Verify

Maybe beyond the scope of Aegir? If install fails because of a bad install profile, would be nice if user was notified.

Install finishes with no errors when a site is setup with the attached install profile. You also don't see errors where Verifying the site.

To fix the error in the attached install profile see: /******** REMOVE next line to fix error *************/

(Obviously, remove the .txt from the attached file.)
