problems with import tags

gnue-forms, gnue-common : 0.5.3
platform: win32


whenever i try to use an import tag in a form I get the following:

DB000: Traceback (most recent call last):
DB000:   File "C:\Python23\Scripts\gnue-forms", line 30, in ?
DB000:     client.run ()

68, in loadFile
DB000:     initialize, attributes={"_instance": instance,
DB000: AttributeError: 'NoneType' object has no attribute '_parameters'

does anybody has any useful example on how to use those tags?
maybe they are just broken an i should wait...
