  # Feedzirra has some issues with failure cases:
  # If the failure occurs on the parsing phase, then the on_failure callback is triggered
  # If the failure occurs on the fetching phase (i. e. a network error), the a number is returned
  # That number may represent an http status code or be 0 in case of other errors.
  # Also, we can't raise an exception on the on_failure callback, 'cause it will be raised even on success - that's really odd
  # So we need this 'safety net' here until we patch it to use an uniform error architecture
