Workbench null pointer exception

I just noticed a minor problem with workbench 0.7.0. When updating the properties for an unfiled object a null pointer exception is thrown. The stack trace shows

If looks like it is trying to reload the folder even though the document is unfiled. This happens as the editor is opened and when the update button is clicked.
