Has anyone ever got an error similar to the one below when trying to import files thru ZCVSMixin (AFTER they were exported from same application) The file was not modified in any way but it refuses to re-import after being exported. Failed Imports /var/workspace//350nice/products/orderitnice/zopecontent/portal_skins/orderitnice/Contacts/addAddress.xml Failed Messages Traceback (most recent call last): File "/var/workspace/350nice/zope/lib/python/Products/ZCVSMixin/ZCVSMixin.py", line 924, in filesToObjects ob=self._container_p_jar().importFile(fname) File "/var/workspace/350nice/zope/lib/python/ZODB/ExportImport.py", line 72, in importFile raise POSException.ExportError, 'Invalid export header' ExportError: Invalid export header
