You should try turning on debug in your settings.pro file and then
running mythfrontend under gdb.  Then you can get a better backtrace
and find out where it's crashing.  You need to recompile after turning
on the debug line of course.

You can also try going down to the Show() function and putting some printfs
in there in the section that gets executed when Xv is not available.
Maybe it's segfaulting in the show routine.

The non-Xv section starts with a few lines like this:

        unsigned char *y_ptr;
        unsigned char *u_ptr;
        unsigned char *v_ptr;
