No need this time, it was just a missing null pointer check, I've fixed
it in SVN.

My guess is this happens when you have captions on by default and there
are teletext captions but no subtitles, then we could try to get the
teletext viewer initialized before the OSD is initialized. Colin does
this describe your situation? If so, does the teletext ever get auto
enabled after this null pointer check is added to the code?
