The problem I reported exists with current master, but maybe I did not
describe it well enough. Let me try once more with a specific file which
shows the problem.  Open the attached file "table.org" in emacs.  Then
do

M-x org-table-export

you will then be prompted with "Export table to:" for a filename, where
you wish to export to.  Note that already at this point two stars appear
in the emacs status line, which indicate that the buffer has been
modified.  This is a bug, as no real modification of the buffer
has happened at this point.  

The attached patch solves the problem for me by only calling
org-table-align if both org-table-automatic-realign and
org-table-may-need-update.  However, I am not completely sure if this is
the correct solution though, I simply used the same idiom as is used in
org-table-next-field and org-table-previous-field functions.
