+ * glocalfileinfo.c: (_g_local_file_info_get):
+ * gcontenttype.c:
+ (g_content_type_get_icon): Implement this function by

+ (g_content_type_get_description): Unalias before getting

+
+ * gfileinfo.h: Add new attributes for filesystem::use-preview
+
+ * gio.symbols: Update
+
+ * gthemedicon.c: (g_themed_icon_append_name):
+ * gthemedicon.h: Add new new convenience function.
+
+ * gunionvolumemonitor.c: (g_union_volume_monitor_dispose),

+ separate object initialization and volume monitor initialization
+ such that non-native volume monitors can properly adopt their
+ mounts away.
