Comment(by candrews at integralblue.com):

 Recompiling yielded a better backtrace:

 }}}
 On line 4, the offending code is: {{{qApp->enter_loop();}}}
 Line 5 is: {{{    return MythDialog::exec();}}}

 Neither of those is an obvious problem. It seems the issue is with QT (but
 not being a QT programmer, I don't know). So... what is the purpose of
 {{{qApp->enter_loop();}}}, and could that be the polling source?
