[mythtv-users] Frontend aborts on selection of secondary audio stream

Using dvb-t in the uk, 64-bit f13 latest from ATrpms

I don't use the 'visually impaired' stream and usually strip it off; I 
came across this yesterday but don't know how long it's been there.  I 
haven't tracked down exactly which programmes are affected.  It doesn't 
happen after Project-X has done the stripping.  mythfrontend -v audio 
log follows.  This programme isn't listed as having a second audio 
track.  I've found one in which the second track played properly and 
others that claim to have such a track but abort.
