It seems you have a host name that resolves to both an IPv4 address and 
an IPv6 address, no? So when DNS returns two addresses for that host 
name, which one should be used? Should bacula-fd listen on the first 
address returned, the second address returned, or both?

FDAddress is retained for backward compatibility. I believe you should 
use FDAddresses for IPv6 and/or multi-homed machines.

Try using something like:
     FDAddresses {
        ip = {
           addr = hostname
        }
     }

The ip keyword of FDAddresses allows selection of IPv4 and IPv6 addresses.

An alternative solution that will work with both Bacula, and any other 
software that may not be as configurable as Bacula, is to assign 
different host names for the IPv6 network than are assigned for the IPv4 
network. That removes the ambiguity, although I still think you will 
have to use the FDAddresses directive as opposed to the FDAddress 
directive. The older FDAddress directive may not support IPv6.
