I tracked the problem down to the following, when my laptop goes online, the results of gethostbyname may
change as well. Unfurtunately, this means that the property name used to find the running ROX-Filer no longer
matches. I'd like to suggest that remote.c should not use our_host_name() to build the unique_id if /etc/machine-id
or /var/lib/dbus/machine-id is present. The contents of those files should be used in preference to the hostname().
