I'm afraid i can't: i ended up in a situation where there were no
registered auth methods, and mistakenly thought that they were not being
registered (i somehow failed to spot the registering calls in
url-do-setup).

So it's not a change in url.el that causes the situation, but something
i do and haven't pinpointed yet: i'll keep an eye and write back with a
recipe.

The other problem with the error message is probably worth fixing, but
of course not a regression.
