Issue #1353 resolved
Images can not be exported. Fails on "os.path.join(filedir, image)" because "image" is an object without string like methods now. More in [[http://groups.google.com/group/satchmo-users/browse_thread/thread/f95e5decfafc5d27|satchmo-users thread]].
Export to "Python" does not work because it is not public serialization format. It is only internal format. It is "internal_use_only".
Low level categories in the tree which have products only indirectly in subcategories are not exported, e.g. <Category: Books>.
If all product and categories are removed and imported again, then is not possible to edit any book or subcategory because parent category Books is not present.
(Error: Category matching query does not exist.)
