Jan, I'm seeing the same error (with Kamailio build from the git master 
def8d26) when I have multiple branches, though mine is proceeded with a 
uri2dst2() error:

ERROR: tm [ut.h:272]: uri2dst2(): ERROR: uri2dst: bad_uri:

Unfortunately, I'm learning Kamailio and trying to work with branch routing 
and I can't figure out if my script is wrong, or if there's a bug.

My script is as follows:

route[LOCATION] {
#!ifdef WITH_SPEEDDIAL
        # search for short dialing - 2-digit extension
        if($rU=~"^[0-9][0-9]$")
                if(sd_lookup("speed_dial"))
                        route(SIPOUT);
#!endif

#!ifdef WITH_ALIASDB
        # search in DB-based aliases
        if(alias_db_lookup("dbaliases")) {
                $avp(oexten) = $oU;
                route(SIPOUT);

        }
#!endif


        if($avp(oexten)==$null) $avp(oexten) = $rU;
        if(!lookup_branches("location")) {
                # Save the return code from the lookup function
                $var(rc_lookup) = $rc;

                if(is_method("MESSAGE")) {
                        route(IMC);
                        route(MESSAGEGW);
                        route(MSILO);
                        send_reply("404", "Not Found");
                        exit;
                }

                # Route to Asterisk
                if(is_method("INVITE") && !is_subscriber("$ru", "subscriber", 
"1")) {
                        route(TOASTERISK);
                        exit;
                }

                # Route to VoiceMail
                route(TOVOICEMAIL);
                t_newtran();
                switch ($var(rc_lookup)) {
                        case -1:
                        case -3:
                                send_reply("404", "Not Found");
                                exit;
                        case -2:
                                send_reply("405", "Method Not Allowed");
                                exit;
                }
        }

        # when routing via usrloc, log the missed calls also
        if(is_method("INVITE"))
        {
                setflag(FLT_ACCMISSED);
        }
}

route[SIPOUT] {
        if(uri==myself) return;

        append_hf("P-hint: outbound\r\n");
        route(RELAY);
        exit;
}
