Thanks for the report!  It looks like the problem is just that
"get_manifest_of" doesn't work on totally new workspaces (ones where
you've run 'setup', but haven't added any files yet).  This is because
of a silly little technicality in how we set up workspaces at the
moment -- every tree needs to have a root directory, but right now
'setup' doesn't create that, instead it's automatically created the
first time you add something.  So, no worries, just add something and
then things will be fine.

Why _don't_ we create the root dir at setup-time?  Graydon, do you
remember?  (I know this came up at some point, but I don't remember
what was said.  Maybe just "oh well, we already wrote it the other
way, why bother switching"?)
