Backup Folder not set

I keep getting this error when the service starts
Jan 05 10:11:54 bbiijaxbkup01.bbiius.net urbackupsrv[21369]: Backupfolder not set
Jan 05 10:11:54 bbiijaxbkup01.bbiius.net urbackupsrv[21369]: Backupfolder not set

Yet the backup folder is set and backups wil be saved there. But, the server will crash after a while and I do not see any other indication of a problem. When it fails I get this message in the logs.
Jan 05 10:10:38 bbiijaxbkup01.bbiius.net systemd[1]: urbackup-server.service: main process exited, code=killed, status=11/SEGV

If you are able you could try to track down the problem using
