The object, I?d like to export is a folder. At least, it shows up with
the corresponding icon. In the navigation frame on the left, the folder
is visible with a "+" in front of the symbol. Clicking the "+" uncovers
a list of sub-objects.
Puzzling is that selecting the folder or one of the sub-objects by
clicking it, the content is viewed at once, not the "manage_workspace" view.

I hope this is the traceback you requested:
