Visiting a non-existing template for a product gets me a system error

The way to implement this is by writing views on exceptions. We need to ensure that the specific case of not finding a template raises a specific kind of not found exception, and then write a 404 page for that exception.

The same approach can be used elsewhere too.

In this case, I think that URL should be killed, so everytime we get the URL:

https://launchpad.ubuntu.com/rosetta/products/encfs

we forward them to https://launchpad.ubuntu.com/products/encfs/+translations

I agree entirely with Carlos.

Note that the problem I am pointing out here is that

https://launchpad.ubuntu.com/rosetta/products/encfs/foo-bar-baz-nothing-here

is plain a 404 error. Actually, it's a system error now that I've checked on it. But

https://launchpad.ubuntu.com/rosetta/products/encfs/

works fine. I would like the page for no-such-template to tell me "this template doesn't exist, but you can see all templates for product encfs <a href...>here</a>.

This seems to have long been fixed (not to mention that URL scheme has changed significantly :).

I.e. https://translations.edge.launchpad.net/products/encfs/template forwards correctly to /encfs/template which gives a 404.
