 Bug moved upstream from Ubuntu, the package in use it was built against
 head at the time. Further files at
 https://bugs.edge.launchpad.net/ubuntu/+source/mythtv/+bug/191291

 Binary package hint: mythtv

 Attempted to use MythPhone to call another computer on the lan (also using
 MythPhone; both computers use the same current Hardy MythTV packages).
 Almost immediately after the call was connected, the frontend process
 died. The receiving computer's frontend kept running as if the caller was
 still connected.

 Neither computer is set to register to a SIP server
 Both computers' microphone device is set to /dev/dsp
 Both computers' Webcam device is set to /dev/video0 with transmit and
 capture resolution set to 352x288, 30fps, 400Kbps.
 The sender's webcam is a Z-Star Microelectronics Corp ZC0303 WebCam
 0ac8:303b (vender is Vimicro) using the gspca.ko module (zc0301.ko is not
 correct for this device despite the similar name)
 The receiver's webcam is the Virtual Video Device (vivi.ko) since it lacks
 a real webcam
 Both devices function without incident using other applications (e.g.,
 Ekiga)
