Hello,

Thank you for the useful reactions, I see there is a tool for sorting the
route file. However, when I run sort_routes.py I get the output "read 0
elements. wrote 0 elements." and no errors. The output file that is
generated contains some comments, but no route data. Now that I think of
it, doesn't the python script need the vehicle file in order to be able to
sort the routes?

I read these reactions just after I sent a mail with an overview of my bug
reports (which also includes this scenario as "sumo_segfault" but then with
screenshot and reduced vehicle file size). So if the crash problem we are
discussing is solved already then you can ignore this scenario that I just
sent again in my bug overview message.

Greetings,
Pieter
