Ah, was that the problem. You reporterd earlier that point_xy was not 
working in index for area, but not that this was the reason. Thanks for 
this new report and with this it is fixed now.

Besides this I also updated/extended the linestring/polygon intersection 
(which is working for intersection and difference now, in all cases that 
I tested. Will do some more test next week.)
