This is an horrible band-aid, it stops the crash - but ... it's hard to live with oneself here. Clearly the arithmetic is going -badly- wrong here, for some reason - and the code looks glass-fragile all about the place ;-)
OTOH the band-aid can't make things worse (or can it - by potentially forcing a re-ordering of the dirtied ordering in the svdpage - urgh).
