I suspect it's another QT5 related issue (have nothing to base that belief on...).  Any suggestions or thoughts on related fixes in master (James is running fixes/31) would be appreciated.

Mostly SuSE Leap 15,2, lubuntu (lxqt) 20.10, xubuntu 20.04 and a sprincle of Debian Buster. Not tried on buster, all rest are fe with suse as be.

Mark before edit on HD resulted in E, <space> one or two moves (<rt> or <left>) and crash.
Now I've done cutlist on half a dozen videos and have prevoked core dump (sig 11) twice.
Posted the trace but it just said line 15 /Applications/Mythfrontend.app/Contents/MacOS/mythfrontend
which is not far from 'something is wrong somewhere'
