Comment (by ajm1@…):

 An additional observation to share.  As noted before the segfault is only
 hit when the backend is started with an initscript.  If the backend is
 started from a shell or within GDB, I am unable to hit the segfault.

 The command line given when starting the backend from a shell matches the
 command line used within the initscript - with the exception of the start-
 stop-daemon.  Could this be related???

 To test this theory, I did invoke the backend once from a shell using the
 start-stop-daemon command line and I '''did hit the segfault'''

 Invocation from command line:
 /mythtv/latest/bin/mythbackend --daemon --loglevel debug -v system
 --syslog local7 --pidfile /var/run/mythtv/mythbackend.pid --noupnp

 Invocation from initscript:
 start-stop-daemon --start --pidfile /var/run/mythtv/mythbackend.pid--chuid
 mythtv --nicelevel 0 --exec /mythtv/latest/bin/mythbackend -- --daemon
 --loglevel debug -v system --syslog local7 --pidfile
 /var/run/mythtv/mythbackend.pid --noupnp
