Comment 2 for bug 660261

The following line, in quick-browser/src/applet-menu.c, is the cause of the error message:

cairo_dock_fm_launch_uri (pItem->cPath);

For some reason unknown to me, gtk_recent_manager_add_item (rm, pItem->cPath) -- in the function cairo_dock_fm_launch_uri() from cairo-dock-core/src/gldit/cairo-dock-file-manager.c -- doesn't work and can't add the new resource into the recently used resources list.
