All Gnome programs use gdk-pixbuf as a graphic library for loading and
saving image files. Since this happens in all Gnome programs for you
(epiphany and mozilla both use other code for displaying images), it is
very likely a bug in this basic library (which comes with GTK).

Does it happen with all kind of jpeg files? This is a 24bit jpeg file, 
which may be the source of the problem. Anyway, could you attach a test 
file where it doesn't work to a bug in our bug tracking system at 
bugzilla.gnome.org? This would be very helpful. Thanks.
