Thank you for your efforts David.
I've implemented the patch and it works in my environment,
backups complete ok and I can do sucessfull restores. :-)
But as you say, the system thinks 0 files got backed up:
2016-01-19 09:48:39 full backup started for share Backups
2016-01-19 10:58:59 full backup 75 complete, 0 files, 0 bytes, 0 xferErrs (0 bad files, 0 bad shares, 0 other)
