That's strange, it means $dev_status == $DEVICE_STATUS_SUCCESS and 
$f_type != $Amanda::Header::F_TAPESTART which should not happen for a 
cleaning tape.

It might be some cache issue, can you send me the 
/var/lib/amanda/chg-robot-dev-sg7 file and retry.

At the beginning of volume_is_labelable, can you add:
     debug("volume_is_labelable sl: " . Data::Dumper::Dumper($sl));
