I get the above mentioned error every time tshark encounters an SNMP reply that
has OIDs with 64-bit counters in it. Please check with the capture file I
provided, the first packet is the SNMP request, the second one is the reply,
the errors occurs while trying to parse the second packet.
I can reproduce this bug on my Fedora Core 8 i386 32bit linux machine at will,
however a 64bit CentOS 4 linux machine can parse such packets without any
problems.
