Franta,
I think the issue is the SNMP supplies/status support that was added in 1.4.x. By default it is turned on unless you have "*cupsSNMPSupplies: False", but for a raw queue there is no PPD file.
Please file a bug for this at:
http://www.cups.org/str.php
I think the resolution for this should be that the SNMP supplies/status support is not enabled for non-PPD/raw queues at all.
