+Subject: 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().
