In org 6.12a from 15-11-2008 I got this error when exporting a file to HTML (using htmlize):

The problem is in org-export-target-internal-links (org-exp.el), in lines:

                        (max (point-min)
                             (1- (previous-single-property-change
                                  (point) 'target)))
                        'target))))))))


 And in fact, if in the org file I eval this:
(previous-single-property-change  (point) 'target)
...I get nil. This is valid according to the documentation (it means the property is constant).
