    Description

      Our users are reporting odd crashes when trying to close dialog or when tree view is being updated/cleared, It is only happening on OS X 10.10/10.11 and we can't reproduce it locally, other platforms are unaffectted. Crashlogs always have something related to NSAccessibility or
      I just hope crash logs will give some clues:
