We're definitely following parallel paths..  I noticed the
libmythtv.pro thing, but I assumed it was not the (only) cause,
because other platforms build okay.   So, I posted to the dev list,
and Daniel Kristjannson recommended building it with the backend
enabled.   I did that (osx-packager -enable-backend), and it built.

I get the same bus error, just after the blue background for
mythfrontend displays.

The output from the MacOS crash report looks like it is a QT problem
when it's trying to display text:
