[Pkg-utopia-maintainers] Bug#908721: firewalld: blocks mdns traffic on home zone (with mdns enabled)

[Sergio Villar Senin]

Package: firewalld
Version: 0.4.4.6-2
Severity: important

Dear Maintainer,

   * What led up to the situation?

   Upgrade to 0.6.1

   * What exactly did you do (or not do) that was effective (or
     ineffective)?

   Using avahi-discover to list discoverable services in my LAN

   * What was the outcome of this action?

   Nothing was shown

   * What outcome did you expect instead?

   Available discoverable services are shown

I've activated mdns for home zone. The home zone is active but the mdns
traffic is blocked. I confirm that downgrading to 0.4.4.6 fixes the issue
with zero configuration changes.
