[Inkscape-devel] Re: refcount rules

SPObject *oldmarker = sandbox->getObjectById("sample");
if (oldmarker) {
    sp_object_ref(oldmarker, NULL);
    oldmarker->deleteObject(false);
    sp_object_unref(oldmarker, NULL);
}

Can't we just add those ref/unref calls to the beginning and the end of the deleteObject?
