Fixed double free that was causing lots of nasty errors in the file
* src/file-manager/fm-directory-view.c: (fm_directory_view_activate_entry): Fixed double free that was causing lots of nasty errors in the file manager. (fm_directory_view_load_uri): Made the old directory hang around a bit longer when loading a new uri. (display_selection_info): (fm_directory_view_send_selection_change): (display_selection_info_idle_cb): Fixed a storage leak and broke out the selection change into its own function instead of mixing it with the status line. Also made the selection actually use URIs instead of just names for the selected items. * libnautilus/nautilus-directory.h: libnautilus/nautilus-directory.c: (nautilus_file_get_uri): Added this function that gets a URI (rather than just a leaf name). * libnautilus/nautilus-directory.c: (nautilus_directory_finalize): (nautilus_self_check_directory): Added more self checks and fixed a bug where a metadata change would get lost if you delete the directory too soon after making the change.
