Again: blobs export as expected.

However, Jeff pickles/unpickles the subtree to get rid of the
'__parent__' attribute. This and blobs' inability to get copied around
in this specific manner make him end up with empty blobs.

From the export mechanism's perspective he simply exported an empty
blob. If the blob had data it would be there.
