LiveTV Seg Fault - UK Freeview BBC SD Channels

Description
mythfrontend seg faults on LiveTV for BBC One (SD) and others. This appears to be due to broadcaster changes to mheg (red button) services for Wimbledon Tennis. I have seen this on mythfrontend 29,30 and current master on Xubuntu 18.04 and Raspberry pi3/4 Buster. This problem has also been observed by a number of people see https://forum.mythtv.org/viewtopic.php?f=36&t=3236
A temporary workround is to change Enable interactive TV in mythfrontend: Mythfrontend Setup>Video>Playback OSD and uncheck Enable interactive TV
Attached are gdb backtrace and mythfrontend log produced on a Xubuntu 18.04 system with mythfrontend built from source: MythTV Version : v31-Pre-506-gc51c7d7beb-dirty MythTV Branch : master Network Protocol : 91 Library API : 31.20190109-1 QT Version : 5.9.5 Options compiled in:

Forgot to mention, playback of previously recorded program from say BBC One (SD) also seg faults. Again uncheck Enable interactive TV workround fixes the seg fault.

This is probably because the extra temporary RedButton channels, 602 to 606, are all DVB-T2.
601 is DVB-T

Please try the patch attached to the ticket. Written against master, but i suspect it'll apply to other releases too.

Yes, I can select various red button screens 601,602,603 etc from both BBC One (SD) and BBC One (HD) using MenuBlue
