Comment (by Klaas de Waal):

 The missing libGLX is a good point, have added this now and the crash is
 gone but now it hangs.....

 Changed settings.pro to add libGLX:

 {{{

 +    EXTRA_LIBS += -lGLX

      # remove warn_{on|off} from CONFIG since we set it in our CFLAGS
      CONFIG -= warn_on warn_off

 }}}

 The resulting mythfrontend does now link to libGLX and it now goes beyond
 the "create" call in which it crashed previously. This is the log now:

 Mythfrontend keeps running but the problem is now that there appears
 nothing on the screen.
