Comment 6 for bug 2046470

Hmm,
when it enters the main loop it initializes a timed check to cope with e.g. changing topology and hotplug.

constants.h:5:#define SLEEP_INTERVAL 10
...
g_timeout_add_seconds(sleep_interval, scan, NULL);

And that function starts like:
 gboolean scan(gpointer data __attribute__((unused)))
 {
     log(TO_CONSOLE, LOG_INFO, "\n\n\n-----------------------------------------------------------------------------\n");

So I guess we know what emits those, the question is why wasn't this seen before.
Because the code to emit that is in former Ubuntu releases, something else must have changed the behavior.
