Bug Description

$ DISPLAY=0 avahi-discover
/usr/lib/python2.7/dist-packages/gtk-2.0/gtk/__init__.py:57: GtkWarning: could not open display
  warnings.warn(str(e), _gtk.Warning)
/usr/bin/avahi-discover:64: Warning: invalid (NULL) pointer instance
/usr/bin/avahi-discover:64: Warning: g_signal_connect_data: assertion 'G_TYPE_CHECK_INSTANCE (instance)' failed
Segmentation fault (core dumped)

Probably a null deref, but still shouldn't happen if a program is checking its return codes for errors.
