Thank you very much! On one hand, this is disappointing because I see no hope for a quick fix, on the other hand I would have never found this problem, and I appreciate your help. Unfortunaltely, there is a popular habit in huwiki to use LT without its beeing ready.
Actually Brion committed one of the first fixes (for the XML output), so it has a chance to be deployed before the next dump occurs.
