Getting Org-Crypt to work (doc bug?)

[David Masterson]

I'm trying to get org-crypt to work, but I'm missing something.
Following the Org-Crypt Info page, I've set it up for symmetric
encryption and added a :crypt: tag to a header.  When I try to save the
file, it reports that no key was specified, so it will do symmetric
encryption.  And then it freezes.  C-g will unfreeze, but the buffer is
slightly messed up like it started working on something, but waited for
an external command? GPG is installed.  What am I missing?
