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.
