[mythtv] PIP Segfault with BT

I get the attached segfault when using picture in picture. Pressing V brings
up the second channel no problem. However when I press B to swap to the PiP
channel so I can change it, it segfaults.
I also notice that once Picture-in-Picture mode is turned on via the OSD
menu, the Picture-in-Picture option disappears from the menu so it's
impossible to turn back off if you don't have V mapped on your remote. Why
does it get removed from the menu?
Isaac, would you like segfaults sent to the bugzilla and then just
referenced on the mailing list? What about patches?
