No firewall, network driver works fine.  Running the commands on the same
machine.  It's definitely not the driver;  I tested both setups (Slack
12.1/0.6.24, and Slack 12.2/0.6.24) on the same machine.  Earlier setup
works fine, latter one doesn't.

Another tester reporter the following, but they are not sure if it may be
causing the conflict:

Here is something I noticed while checking out Avahi, here are the
registered file descriptors:

Of those, only 0, 1 and 2 are existing, all the other pipes/sockets and
inotify are currently not there, by running Strace, it appears that it
gets stuck reading those sockets that are apparently not pointing anywhere:

poll([{fd=3, events=POLLIN}, {fd=13, events=POLLIN}, {fd=12,
events=POLLIN, revents=POLLIN}, {fd=11, events=POLLIN}, {fd=10,
events=POLLIN}, {fd=9, events=POLLIN}, {fd=8, events=POLLIN}, {fd=7,
events=POLLIN}, {fd=5, events=POLLIN}], 9, 423685) = 1

On 12.1, at least some of those sockets seem to be pointing somewhere.
Just a guess though.

I haven't had a chance to verify this yet.  How could we go about testing
some more?
