[mythtv] Frontend segfault when viewing onscreen guide

This is from attempting to view the onscreen guide with HDTV or SD picture-in-window (from watching live TV, press "S"). It displays for a time, then crashes as I move around the guide. I'm running from current CVS.
Attached are 3 backtraces:
Program received signal SIGSEGV, Segmentation fault.
