I re-fetched the latest development release from today (March 30, 2010), and I
also built and installed libpcre and libsmi as per request.  As per the
original test (SNMP get-response for sysName), I captured the SNMP transaction
using Wireshark v1.03 and saved the file.  I then opened the file using v1.3.3
and witnessed the same problem.

v1.03 decoded the packet as:
            variable-bindings: 1 item
                1.3.6.1.2.1.1.5.0: 6C6F63616C686F73742E6C6F63616C646F6D61696E
                    Object Name: 1.3.6.1.2.1.1.5.0 (iso.3.6.1.2.1.1.5.0)
                    Value (OctetString):
6C6F63616C686F73742E6C6F63616C646F6D61696E

v1.3.3 decoded the packet as:

            variable-bindings: 1 item
                1.3.6.1.2.1.1.5.0:
                    Object Name: 1.3.6.1.2.1.1.5.0 (iso.3.6.1.2.1.1.5.0)

Note that the issue is not with respect to OID resolution, but with the missing
'value' information.

Note also that in this version, Edit > Preferences > Name Resolution > Enable
OID resolution does not exist.

For the record, this re-built version now reports:
