Tried changing the wchar array initialization from:
m.MediaLabel = u'x' * 65
m.MediaDescription = u'y' * 257
m.Barcode = u'z' * 33
To:
m.MediaLabel = [ u'x' ] * 65
m.MediaDescription = [ u'y' ] * 257
m.Barcode = [ u'z' ] * 33
omniORBpy stopped SIGSEGV'ing but looks like marshaling errors are occurring
when talking to a TAO server from an omniORBpy client
omniORB: throw MARSHAL from cs-UTF-16.cc:347 (YES,MARSHAL_InvalidWCharSize)
Here is more trace output.

Subject: [omniORB] SIGSEGV in marshalPyObjectWChar
While using omniORB-4.0.3 and omniORBpy-2.3 on a Linux RHAS 2.1 machine I'm
experiencing a crash in the marshalling code of omniORBpy. Any suggestions
on how to get through this problem would be greatly appreciated.
Thanks,
Joel
Here is an excerpt from the Python script that causes the problem.
m = V.M.Create_Args
m.Key = 0
m.Label = u'x' * 65
resp, out = session.Create([m], 0)
Here is the corresponding IDL:
struct Create_Args
{
long Key;
wchar Label[ 65];
} ;
typedef sequence<Create_Args> Create_Args_Seq ;
unsigned long Create( inout Create_Args_Seq Arguments, in unsigned
long Flags) ;
Here is the stack trace:
omniORB: Invoke 'Create' on remote:
