i have done further tests with regard to this and i have established that it is the plugin zeitgeist that is causing the crashing. the way i tested this was i disabled all plugins and tested it. then reactivated each plugin one by one.
terminal output when i ran rhythmbox from terminal. rhythmbox (rhythmbox:2440): GLib-GObject-CRITICAL **: Custom constructor for class SoupServer returned NULL (which is invalid). Unable to remove object from construction_objects list, so memory was probably just leaked. Please use GInitable instead.
