[mythtv-users] not detecting it's master when not using 127.0.0.1

[Brian J. Murrell]

I have an 0.22 backend here:

Please include all output in bug reports.
MythTV Version   : 22750
MythTV Branch    : branches/release-0-22-fixes
Network Protocol : 50
Library API      : 0.22.20091023-1
QT Version       : 4.5.2
Options compiled in:
 linux profile using_oss using_alsa using_pulse using_jack using_backend using_dvb using_firewire using_frontend using_glx_proc_addr_arb using_hdhomerun using_hdpvr using_iptv using_ivtv using_joystick_menu using_libfftw3 using_lirc using_mheg using_opengl_video using_opengl_vsync using_qtwebkit using_v4l using_x11 using_xrandr using_xv using_xvmc using_xvmc_vld using_xvmcw using_bindings_perl using_bindings_python using_opengl using_vdpau using_ffmpeg_threads using_libavc_5_3 using_live using_mheg

and when I configure both of the backend IP addresses to 127.0.0.1, it
correctly determines it's the master backend:
