Can you try running with both "trapsink" and "trap2sink" lines, but
referring to two different IP addresses?
   I suspect that this will also run without complaint, and that it's
having two entries referring to the same destination that triggers
the problem.   (I'll try & check this later)

An entry such as
     trap2sink  192.111.111.1  pulic 162

will accept a request to send a notification in *any* format (whether this be
send_v2trap(),  send_easy_trap(),  an AgentX notification, or whatever),
and generate the appropriate SNMPv2 trap.

Similarly, an entry such as
     trapsink  192.111.111.1  pulic 162

will accept exactly the same set of requests, and generate the equivalent
SNMPv1 trap.  The mechanism used to specify the trap has *NO* effect
on the version of the trap actually sent out.

Please see the FAQ entry
    How can I get the agent to send an SNMPv1 (or SNMPv2c) trap?

You should *never* (normally) need to have two "trap*sink" lines referring
to the same destination.  That would result in two copies being generated
for every trap.
