Problem with importing with transmogrifier

I am trying to migrate some content from a Plone 4.0.7 site (running on
Windows 2003) to a Plone 4.3.1 test install (running on a Windows 7
machine).

When I tried to import the tarball on the new site, here is the traceback I
got:


Traceback (innermost last):

   - Module ZPublisher.Publish, line 60, in publish
   - Module ZPublisher.mapply, line 77, in mapply

   - Module quintagroup.transmogrifier.reader, line 96, in readFiles
   - Module Products.GenericSetup.context, line 355, in readDataFile

AttributeError: 'NoneType' object has no attribute 'read'


Checking the Products.GenericSetup.context code, on the readDataFile
method, it has two parameters, filename and subdir.

I debbuged to see what were the values for these parameters. It seems like
quintagroup.transmogrifier.reader is calling that method passing not only
the xml files contained in the tarball, but also the directories. The error
happens because readDataFile tries to extract the "file", passing the
directory name (line 347), and then tries to read it (line 352), but since
extractfile returned None, there was no read method.

Has anyone encounter this issue before? Any workarounds?

Thanks in advance.
