For testing purposes, I start the FE this way:
DISPLAY=:0 /usr/bin/mythfrontend --service &
--------------------------------
This case operates reliably:

Enter LiveTV
Tune 3-4 channels
Use wired keyboard letter ""h"" to go back in channel history
(I can repeat this several times, no crash)
--------------------------------
This case segfaults...:

Enter liveTV
tune 3-4 channels
Use command line ""nc localhost 6546 < mythcmd""
-- where 'mythcmd' contains only text ""key h"" (no quotes in file)

After 1-2 calls from the command line (call script, wait for channel to tune, call script), the FE crashes.
No errors produced in FE logs, even with -v channel,socket


[1]+  Segmentation fault      DISPLAY=:0 /usr/bin/mythfrontend -v channel,socket
------------------------------------


I'm sure I need to tell you more, do I need to take this to the bug reporting tool or am I trying to make something work in the wrong way?
