    gsm: Make fatal errors exit after error dialog during initialization
    
    While we're setting up everything, there is no main loop, so calling
    gtk_main_quit() usually won't work and the user will be stuck with an
    empty session after the error dialog. So simply call exit() if there is
    no main loop after a fatal error.
