Working DAB receiver for SDR in GNU Radio?

Hej, Is there a working implementation of a DAB receiver for SDR (GNU Radio implementation). I understand that there are DAB receiver applications that can run on rtl-sdr like the qt-dab or But is there any implementation of DAB receiver part in GNU Radio. I have tried working with the gr-dab but was not successful in making it work. I am not sure if am not running the gr-dab module correctly or there is some problem with the gr-dab module. Can someone confirm me the working of gr-dab module or suggest me with sources for DAB receiver?
