I ran into a similar problem with org-agenda-prepare-buffers and the
EFFORT property. This change to org-refresh-properties seems to fix it:

The previous version by Bastien used (org-end-of-subtree t t), which had
checked for (eobp) in it, but outline-next-heading returns nil if there
are no further headings.
