Bug 650716 contains the apport data from another instance of this crash/bug, reproduced immediately after the one in this report. I thought it might be useful for comparison's sake. It seems this might be the cause (from .xsession-errors):

(nautilus:1323): Gtk-CRITICAL **: IA__gtk_widget_set_child_visible: assertion `GTK_IS_WIDGET (widget)' failed
(nautilus:1323): Gtk-CRITICAL **: IA__gtk_widget_size_allocate: assertion `GTK_IS_WIDGET (widget)' failed

I tried ejecting using File->Eject, which worked successfully, as well as Safely Remove Device. Since doing these (and emptying the trash in the process), I can no longer reproduce the bug.
