I've decoded that packet, and it looks OK to me.
(It's walking part of the ipAddrTable)

There's not really enough detail there to be useful.
All that occurs to me is that wireshark is expecting the
request ID to be 4 octets in length - it's actually 2.
(i.e. your client is sending a 16-bit ID)

That's not really much help either, since it only show the successful
conversation
(up to the atTable).
Can you try running a GETNEXT request (*not* a walk) on the OID
.1.3.6.1.2.1.20.1.1.10.60.3.1
Does that trigger an error or not?
If not, then try running a GETNEXT on the OID that this returns.
Keep going until you either get to .1.3.6.1.2.1.4.21.1.1.10.127.0.0.1
or the request fails.
Other things to try:
walking the ipAddrTable
walking the ip group
using SNMPv1 rather than SNMPv2c
