Mateusz,

I read through the bug and it looks like you have it correctly 
understood. I think this would be a good additional check for tile4ms. 
Please prepare a patch and attach it to the bug or open a new bug 
against tile4ms and attach it to that. I think Steve Lime will probably 
be assigned to it by default. It will be good to have ogrtindex and 
tile4ms behaving the same way.
