Incomprehensible error concerning identical babel config for bird and bird6 (bird-v1.6.4 on ubuntu18.04.1)

[Christoffer Hansen]

Hi fellow bird users.

I have a question concerning the syntax error message shown below for
the bird daemon. But NOT for the bird6 daemon. Even thou the
configuration snippet in bird.conf & bird6.conf is identical.

Any educated guesses as to what might be causing this?

cat /etc/bird/bird.conf
(...)
36 # babel
37 ########
38
39 protocol babel {
40   interface "wg-server" {
41     type wireless;
42   };
43   export where (source = RTS_DEVICE) || (source = RTS_BABEL);
44 }
(...)

$ bird -p
bird: /etc/bird/bird.conf, line 39: syntax error

cat /etc/bird/bird6.conf
(...)
36 # babel
37 ########
38
39 protocol babel {
40   interface "wg-server" {
41     type wireless;
42   };
43   export where (source = RTS_DEVICE) || (source = RTS_BABEL);
44 }
(...)

$ bird6 -p
<<empty_output>>

Regards,
Christoffer
