I'm reposting this one with a right title (sorry for the troubel) Hello, A friend of mine has an UnpicklingError when she imports a simple zexp file (DTML method with northing but text and a simple form button) at root level. Her Setup : * She has a fresh Redhat 7.0, python 1.5.2 * Zope 2.3.3 compiled from source * imported some products (cookieCrumbler, nfgnav, yahaw, popoto) My setup : * win 98 * 2.3.3 binary The imports also works fine on NT/2.3.2 All works fine on her machine untill she does the import. Otherwise, nothing wrong. The "bad" .zexp is a simple DTML method export (only text and a form) from the Win98 machine. Any idea about that ? I saw in the archive that this happens sometimes, but with no responses about the reason. We can provide the Data.fs for investigation if needed. Thanks a lot.
