[mythtv-users] seg fault on mythfrontend start

[Preston Crow]

I just upgraded to the latest trunk sources, and I'm getting a segfault 
when mythfrontend tries to start.  It's coming from main():
     new QApplication(argc, argv);
Any thoughts as to what is wrong?  I have qt-4.8.  I was going to 
downgrade, but Gentoo specifically blocks downgrading qt, as apparently 
that is not safe for some reason.
