`music_directory` command fails with proto(NotOk)

[hardfau1t]

music_directory method on Client connected via unix socket fails with proto(NotOk)

client.music_directory() = Err(
    Proto(
        NotOk,
    ),
)

I was able to look into the issue and found out that this method calls config command first and then calls read_pair in that read_pair it tries to check for protocol status (expecting for OK), but config command return even more configs like playlists dir and etc, thus it interprets it as failure, eventhough OK is present after that line
