Bug#1147213: gvfs-daemons: asyncio ERROR(pid 6859): Exception in callback MulticastHandler.read_socket()

[Francesco Potortì]

Package: gvfs-daemons
Version: 1.60.0-2+b1
Severity: minor

I got this in the syslog.  It was a one-off issue, with apparently no consequence, that's why I
set severity to minor.  I was working on my server / desktop box as usual, maybe using Qgis but
I am not sure.
