    Startup: Do not crash when reporting check problems.
    
    * glom/main.c: Instantiate the Application earlier, to ensure
      that GTK+ is ready for use.
      Also call gtk_init() explicitly because Gtk::Application needs
      a fix for this anyway, and it would be nice to use this fix
      in Glom versions that do not need a newer gtkmm.
    
      Bug #680411 (Bjørn Lie, Dominique Leuenberger)
