[omniORB] CORBA::BAD_TYPECODE from omniORBpy servant

[Harri Pasanen]

I'm using omniORBpy to write test programs for our internal CORBA
servers.
The servers are done using omniORB 2.8. For testing I've tried both
omniORB 2.8,
omniORBpy 1.2 and omni3_develop,  omnipy1_develop from CVS, with
identical results.

When I create a callback object in omniORBpy and pass that to the
server, I successfully get some calls back, but most of the time the
server catches
CORBA::BAD_TYPECODE exception.

The message passed to the callback object is:

  struct Message
  {
    unsigned short time_to_live;
    string source;
    string subject;
    any data;
  };

If I run with -ORBtraceLevel 1000, I see the following:

omniORB: throw BAD_TYPECODE from pyTypeCode.cc:2286

We have a C++ client with omniORB 2.8 that talks successfully to the
server, so I presume the omniORBpy any handling is somehow at fault.

Any ideas?   If you want more complete trace info, I'm happy to provide
that.
