Nope, it's still supposed to return DEFER on ERROR; I wonder if this
isn't an off-by-one error, and we'd catch it if we searched for ERRO.
:-)

    if((p = Ustrrchr(av_buffer,':')) == NULL) {
        ...
    }


    /* strip filename strip CR at the end */
    ++p;
    while (*p == ' ') ++p;
    vname = p;
    p = vname + Ustrlen(vname) - 1;
    if( *p == '\n' ) *p = '\0';


    if ((p = Ustrstr(vname, "FOUND"))!=NULL) {
        ...
    }
    else {
        if (Ustrstr(vname, "ERROR")!=NULL) {
            ...
            return DEFER;
        }
    }


Ciao,
