function pageroute_create_path sets empty value to url (%20%F2)

for some reasons the var $next is empty
so when we pass the function: pageroute_create_path(&$page, $next);
near Line 321 and set the array $path

$path = array($page->route->path, $next);

we have an empty value at array Position [1] (2)
this will later implode the path to a URL/Path with .../%20%F2/...
in it. This can cause strange errors!

I changed the line at the top to:

 isset($next) ? $path = array($page->route->path, $next): $path = array($page->route->path);
