[Zope] TypeError in TransparentFolderPatch

[Wolfgang Strobl]

After exporting/importing/copying a folder (say: xyzzy) around, which itself contains a 
transparent folder, from one Zope installation to another I'm plagued by the following error 
message which is quoted below.

Error Type: TypeError
Error Value: illegal argument type for built-in operation

The error happenes when I try to import the xyzzy.zexp into the root folder of the target zope. 
Importing xyzzy.zexp into an arbitrary subfolder (say: t) works, but then the very same error 
occurs when trying to copy/paste t/xyzzy to where it belongs: to the root.

Any ideas? I haven't read through TransparentFolderPatch enough in order to understand what it 
is trying to do here.

Context: Source: a Zope 2.3.1b1 on OSF1, Target,  Zope 2.3.2b1 on Win2000p
