Ok, I'm nearly there. An excerpt from the trace log (which has been expanded
a bit by additional logging). id 301 is the one we are looking for.

This is wrong. Data has been inserted in the wrong block and because data is
now no longer in the right order, idl_intersection (which has been
optimized) fails.

I'm still investigating this further..
