Right, so I'll apply your file (as there is no better option I can think of). 
Hmm, maybe a small tool that helps people to check whether their scan file is 
still ok or to actually produce a valid&correct scan file (from another scan 
file or whatever) would be feasible - let's see ... (this should simplify 
users to deal with that stuff so that more involvement is possible in cases 
where no authoritative source of information exists).

Thanks,

Christoph
