[Catalyst] Spaces in urls

[Harold Frayman]

I have just moved a developing app on to a production server which is
running up-to-date (among other things) Catalyst -- 5.64 against 5.55 on
my development machine. Suddenly the request->path contains %20 rather
than spaces in urls that have them -- which screws up all sorts of things.
Could this be down to Catalyst and/or Cat helpers/plugins or should I be
looking elsewhere?
