Thanks for the bug report, I can confirm this is happening.

I encountered a similar bug where org-agenda-prepare-buffers was causing 
the same issue when the file hadn't been saved to disk, and I agree that 
the solution looks good. I've formatted this into a patch and attached 
it. Might be worth considering too if this is happening anywhere else 
too, since this is the second time it has come up.

Subject: [PATCH] lisp/org.el: Fix org-update-statistics-cookies error

* lisp/org.el (org-update-statistics-cookies): Replace
usage of `org-map-entries' with `org-map-region' to prevent bug where
an error was thrown if the current buffer had not yet been saved to disk.
