mythfrontend crash on starting playback

Description
The frontend crashes consistently on trying to playback certain recordings but only if they are not the first recording played back after mythfrontend is started. I think I am correct in saying that all my recordings will playback if they are the first to be played.
I have not established what is special about the ones that it crashes on. In my experimentation I have been using two recordings of the same show, on the same channel, using the same card, that were recorded 24 hours apart. One shows this problem and one doesn't These are HD recordings from Freesat in the UK. The problem is not specific to this though I get the same symptom on some recordings from an SD broadcast from DVB-T.

My crash reports for the same issue (one from a remote frontend and the other from the backend) are :- https://bugs.launchpad.net/mythbuntu/+bug/1041788 https://bugs.launchpad.net/mythbuntu/+bug/1041797
Further testing has shown that the crash is intermittent when mythpreviewgen is generating the preview. It only seems to affect BBC channels (SD, HD on both UK Freeview and UK Freesat)
Manually running mythpreviewgen on an affected recording can cause the crash about 50% of the time.

I've attached two logs (one a crash the other played back ok) from mythavtest --loglevel debug -v general,playback,libav using the above sample.
It's seems to be hit or miss if it plays back. It can play back times then crash on the next attempt.

So far I am unable to reproduce this problem when building v0.26-rc-23-gb5fbc74 (with or without patch http://pastebin.com/7Pj1Kjke) locally but the problem is still very repeatable when same the version is installed via mythbuntu packages (Original report was from using mythbuntu packages)
