Well, I was trying to store a DirectoryView object in the session so I could get
to it easily from a multiple-frame page.
Of course, this means the DriectoryView gets committed to a storage.

Now DirectoryViews have FSPythonScripts as attributes, so I'm guessing that when
the DirectoryView gets committed to the TemporaryStorage, the FSPythonScripts do
as well.

...and apparently they don't like being pickled :-(

Any ideas?

cheers,

Chris
