It's fixed, though I would like to discuss it a bit more. It *seems* to me that the Zope HEAD is being more picky about storing acquisition wrappers, which on one side is a good thing. OTOH, it was relatively hard to track it down, meaning several visits to gdb. The fact that the parameter is called 'Wrapper' at 'Wrappers_are_not_picklable' makes it even harder, because is practically impossible to cast the object to a Wrapper. So, I would like to propose two changes: 1. Rename the 'Wrapper' parameter to 'wrapper' in that function 2. Include 'Wrapper->container' and 'Wrapper->obj' in the traceback, in order to make it easier for people to find out where is the problem when it happens. (note that the 'Wrapper' parameter is not even being used currently) Thoughts? -- Sidnei da Silva <[EMAIL PROTECTED]> http://awkly.org - dreamcatching :: making your dreams come true http://plone.org/about/team#dreamcatcher "Don't fear the pen.

Answering my own question, a visit to gdb showed that the problem was
not the newBaseUnit, but an object that it was referencing. Its fun
that it didn't happen with 2.7.
