Hi,

I've forgotten whether this is a top post list or a bottom post list.
Sorry.

Somebody posted that the fix is only in 0.27, I was running either
mythtv-backend_2%3a0.26.1+fixes.20130906.dbdd455-0ubuntu0mythbuntu1_amd64.deb
or
mythtv-backend_2%3a0.26.1+fixes.20130914.bd7198b-0ubuntu0mythbuntu1_amd64.deb
when the error popped up.

I'm surprised that that information was not captured automatically,
there was a very large data transfer.
