[mythtv] NuppelVideoPlayer::AutoCommercialSkip () related segfault

[Jelle]

Hi,

I had a segfault in mythfrontend yesterday (with latest or nearly latest 
CVS):

I happened when watching a show while it was being recorded, and the 
commercial flagging was running on it in the background. I think I was 
watching a part old enough so that it had already been processed by the 
commercial flagger (but I'm not 100% sure about that).

Unfortunately, it's not something I think I can quickly reproduce, but I 
did get a core dump, and below is the backtrace that gdb gives on it 
(functions, but unfortunately no line numbers).

An interesting thing may be that I have "Skip Unflagged Commercials" 
off, and "Automatically Skip Commercials" to "Notify, but do not skip". 
And the crash did not happen close to a commercial break.

(no debugging symbols found)
Core was generated by /usr/local/bin/mythfrontend'.
Program terminated with signal 11, Segmentation fault.
