  I reported the bug:

  It check for subclasses of ZODB.broken.Broken, where
  OFS.Unintalled.BrokenClass based one are not. But this is only for
  things inheriting of persistent, where Extension classes (like
  OFS.Uninstalled.Broken...) does come from Persitance.

  ExtensionClass that breaked it.
