Package: org-mode In org.texi in Emacs trunk, there is an Info node named "org-crypt.el". Periods are not allowed in Texinfo node names, so please could you rename this to something else (sadly makeinfo does not warn about such things).
(You might also want to let Texinfo figure out all the node pointers automatically, ie everywhere replace @node Name, Prev, Next, Up with just @node Name This makes it much easier to rename nodes.)
