SNMP walk is not workin after update to 15.1.2

Did you ever come to a resolution on this issue. We are facing this exact same issue. The only difference being that ours our brand new i5800s on 15.1.3. All SNMP config/allowed addresses/community config is good. works from localhost but not on the mgmt ip

Note: the local attempt works on 127.0.0.1, but not on the mgmt IP when testing locally, leading me to believe that the daemon is not listening appropriately to connections from that interface.
