typo3conf/ext/powermail/Classes/Finisher/FinisherRunner.php:54 states "!isset($dpSettings['config'])" , where $dpSettings is only defined in the DataProcessorRunner and not in the FinisherRunner class. There it is called $finisherSettings. This leads to eliminating any "Config" passed to a finisher when run. plz fix.
clearly a copy&paste error in 112e76a
