    gnome-bg: Fix crash when system clock is behind start date
    
    The 1-slide background included in Fedora 17 causes a crash
    in gnome-bg when the system clock is set behind the date specified
    in the slideshow xml file.
    
    This was due to slide->duration being set to UINT_MAX (to indicate a
    single-slide show) but show->total_duration not being updated to take
    account of this. The calculation in get_current_slide() was therefore
    confused, and triggered a g_assert_not_reached().
