[Pkg-utopia-maintainers] Bug#1132800: Upstream fix

[Tj]

After reading through various upstream issues I discovered an issue for 
this:

https://github.com/avahi/avahi/issues/668

It is referenced in PR

https://github.com/avahi/avahi/pull/844

But that appears to have been closed with no explanation and without 
being merged.

It has links to another repository that contains the fix:
