Some further information on this.

Firstly clarifying that the problem is not related to the contents of
the srt file as far as I can tell.  It fails even with the simplest
srt file.

Secondly I have pasted the log from a working run, without the
subtitles,  in case that is useful - http://pastebin.com/KbCvn29V

Hopefully someone can help me.
