It looks like a slip on my part.  In all other places in org-odt.el, I
do

    (with-current-buffer (find-file-noselect )

      )

When an error is thrown during the export process, the buffer will be in
modified but unsaved state.  I forcibly mark the buffer as modified
before killing it.

Let me put in a fix in Org repo.  Next merge will take care of this
issue.
