[mythtv] Crash while navigating recorded programs.

I was running mythtv in gdb since this had happened before. This is on a
front-end machine, with the backend on another server. I leave mythtv
running all the time, so it was was on at the first screen where you
select Watch TV, watch movies, change settings, etc. I went to the Watch
Recordings tab, and came to the list of recorded programs, but I couldn't
scroll up and down between shows. In gdb, mythtv had segfaulted. I've
seen this a few times before, crashing while scrolling through recorded
programs. It was fine the next time I started mythtv, though it actually
didn't take too long for it to crash again, again in the same area
(PlaybackBox::cursorDown).
This is using the CVS version of mythtv from Jun 30, at about 11 pm
Pacific. I looked through the commits and didn't see anything that might
have fixed it since then, but I could be wrong. :)
