Hi continue to have this problem? how could debug it to understand at
least where the problem is?

I would like to know if the problem is on mapnik integration with
mapproxy or if the problem in on our machine. I try to replicate this
error but I cannot, I create a local copy and all is working well

Thanks a lot
