Passing a route object in provider based url generator fails for error messages

[dawehner]

Provider based url generators allow you to pass in not just the name of the route,
but also the route object itself.

    public function generate($name, $parameters = array(), $absolute = false)  {
    if ($name instanceof SymfonyRoute) {
        $route = $name;
    } elseif (null === $route = $this->provider->getRouteByName($name, $parameters)) {
        throw new RouteNotFoundException(sprintf('Route "%s" does not exist.', $name));
    }

If you do that the doGenerate() method is called on the base url generator, which then potentially uses this $route object in the debug messages and break.

Idea: Use getRouteDebugMessage() in the base url generator somehow

Provider based generators are part of the Symfony CMF project, not of the core Symfony. Please report it to their team: https://github.com/symfony-cmf/Routing/issues
