Org buffer corruption with ediff-files

Hi all

There seems to be a bug when ediff-files is used to compare and edit
two Org files. Reproduced with Emacs 24.4 (-Q), today's
release_8.3beta-750-gb6fce5 and these steps:

1) M-: (ediff-files "a.org" "b.org")
2) Move point to the buffer "b.org" to the line with "b"
3) M-<up> M-<up>
4) Move point back to Ediff Control Panel
5) !

The result is that an unexpected difference is left: In the buffer
"b.org" the last two lines with "f" and "g" have been removed.
org-element-use-cache set to nil does not make a difference.
