    Smoke-test gnome-initial-setup --help
    
    Initial Setup is currently crashing on startup in GNOME OS with:
    
        (process:2603): libsoup-ERROR **: 07:05:13.282: libsoup2 symbols
        detected. Using libsoup2 and libsoup3 in the same process is not
        supported.
    
    This is because Initial Setup was built against soup3 and with parental
    controls enabled; unfortunately, malcontent-ui links to libflatpak and
    libostree which are currently built with soup2.
    
    Similar scenarios may occur in the future. In lieu of an actual test
    suite, test that 'gnome-initial-setup --help' succeeds.
