Comment (by scottadmi@…):

 Apologies, my use of "segfault" in the title was incorrect (so there
 wasn't a kernel dump). It was an assertion failure in the linked iec61883
 library - the specific line is "assert (mpeg != NULL);". There was no
 backtrace printed to the console or followup log data at any log level,
 simply after the second channel change:

 {{{
 mythbackend: mpeg2.c:113: mpeg2_recv_handler: Assertion `mpeg != ((void
 *)0)' failed.
 Aborted
 }}}


 If there is a way for me to produce helpful backtrace point me in the
 right direction. The version output is:
