The SNMP TRAP data is displayed not decoded. The value are displayed as "raw
data" (See the attached screenshot).

The OID value of the trap are correctly decoded and this means that the MIB
file that contain the declaration are loaded (See the attached screenshot).

The problem happens on Wireshark release 1.8.0 and 1.8.1.

The problem was not present on Wireshark release 1.6.8 and previous version.

The problem is systematic.
