Tvheadend

I recently updated to tvheadend 4.2.2-64~g0cbd8a1~xenial, and the over-the-air electronic programme guide stopped updating (according to the log, it was still performing the scans, but no new programmes were added).

I then rolled back to an older version, tvheadend 4.2.2-47~ge359705~xenial, and the EPG updates fine.

Does anyone else have this problem (is it a bug or is it there something special in my setup)?
