I have seen a similar report recently (--> mailing list archives).

I must say, I do not know what is wrong. Apparently, everything
is as it should be.
With one exception:

  The traceback contains a strange entry: "zpublisher_exception_hook".

This suggests that what you see is a secondary exception.

These secondary errors make analysis of the primary error difficult.
When I run into such a case, I modify "ZPublisher/Publish.py"
near line 106 in the following way:

        if transactions_manager: transactions_manager.abort()

        # DM
        import traceback; traceback.print_exc()
        
        if err_hook is not None:

This prints the primary exception to standard error - for analysis.

Be aware, you will get lots on exceptions printed that are
harmless: "Unauthorized", "Redirect" and so on.

You are only interested in the output immediately before your
error occurs.
