Attempting to insert a schema-invalid doc gives 'memory manager' error

Question

Hi
I can successfully insert schema-valid XML documents into my BDB XML database by adding the appropriate xsi:schemaLocation elements to the document root element. However, when I intentionally remove a mandatory element from the document in order to make it invalid, for testing purposes, I receive (actually, trap) the following error message:
"Exception code 0."
"Error: nsToUTF8: no memory manager File: NsUtil.cpp Line: 159"
whereas I would expect to see a message relating to validation errors. Looking at the source file NsUtil.cpp I can see that the code is trying to use a memory manager to deallocate some memory. I don't know how this relates to document validation and I'm not about to go fiddling with this particular piece of code!
So, has anyone else encountered a similar problem, or at least have an idea as to what's going on here?
We're using BDB XML 2.3.10 on Linux. And we're accessing BDB using the python interface. My code looks like this (with some bits removed for clarity):
stream = mgr.createLocalFileInputStream(filename)
doc.setContentAsXmlInputStream(stream)
docValue = XmlValue(doc)
cntnr.putDocument(txn, doc, uc, 0)
Thanks in advance,
Phil

Phil,
Try this patch. It'll probably be official soon:
