[Fle3-dev] Import failure FLE3 1.4.2 to 1.4.4

[Ulrich Agricola]

I try to import a file exported from fle3 1.4.2 into a newly set up
fle3 1.4.4. eml.zip is located in /zope/2-6-1/import. Zope cannot
handle this, but gives an eror:

> Zope Error
> Zope has encountered an error while publishing this resource.
>
> Error Type: IOError
> Error Value: [Errno 22] Invalid argument

The zip-file seems ok (I can see twelve data_xy entries an a
fle_eml.xml entry within powerarchiver). 

Anything to do with permissions? I extracted FLE as root ...

Things look well if I create a new empty FLE instance.
