[Zope-dev] Import I/O error

[a32955@pop-server.nc.rr.com]

I've exported a folder from a 2.3.0 Zope installation and am trying to 
import the reulting myfile.zexp into a 2.4.1 installation on a different 
machine.  This causes an IOError as documented below.

The problem seems to have something to do with changing the ownership.

Choosing 'Take ownership of imported objects' before clicking the Import 
button causes the IOError immediately.

Choosing 'Retain existing ownership information' results in an apparently 
successful import, but when I click the imported Folder in the Zope 
management interface, the same IOError results.  In other words, the folder 
gets imported, but I cannot view it, even if I'm logged in as root.

Any idea what's wrong?  Does it have something to do with the differing 
versions on the two machines?

Joe
