I'm seeing a steady stream of log_kioremote messages in .xsession-errors, like:

log_kioremote: RemoteDirNotify::toRemoteURL( QUrl( "file:///export/home/orion/fedora/scilab/scilab-5.5.2/modules/helptools/images/editvar_libreoffice.png" ) ) log_kioremote: result => KUrl() ("196290", "196289", "196288", "196287", "196286", "196285", "196284", "196283", "196282", "196281", "196280", "196279", "196278", "196277", "196276", "196275", "196274", "196273", "196272", "196271", "196270", "196269", "196268", "196267", "196266", "196265", "196264", "196263", "196262", "196261", "196260", "196259", "196258", "196257", "196256", "196255", "196254", "196253", "196252", "196251") ()

why? How can we shut it up? Where should I file a bug?
