[mythtv] ASSERT failure in QList<T>::operator[]: "index out of range"

[cal]

I haven't spotted anything in recent dev/ticket traffic that seems related,
so I just might be alone with this one. At trunk 17144, I'm getting an
"index out of range" QList assert in a couple of places. One example is 

 Utilities/Setup -> Setup -> General -> <Esc>

resulting in -

I'm quite happy to ignore it and just wait for it to go away, but if anyone
spots a genuine issue in it, well that's cool too, happy to help in any way.

cheers, Cal
