[mythtv] Patch: segfault caused by mythcommflag

[Edward Wildgoose]

Mythcommflag seems to use NuppelVideoPlayer to decode the stream, however,
when the aspect ratio is changed then the ReinitVideo is called, which in
tern calls OSD::Reinit.  However, OSD was never setup -> segfault

Following trivial patch seems to fix this:
