picard: lookup takes longer without netlink

[haplo]

I noticed that when running Musicbrainz's Picard with firejail I see the following log errors (in journalctl):

python[18053]: Could not create AF_NETLINK socket (Operation not supported)

An easy solution is to add this to picard.local:

protocol unix,inet,inet6,netlink
ignore protocol

However I'm not sure whether Picard really needs netlink, it seems to work without it although sometimes the lookup hangs for a long time, or never finishes and I have to restart.

Any ideas?

This message is common when netlink is blocked.

If it causes major issues, then it would be good to add netlink to the protocol
list.
