This bug is not in any ways related to bug #581383. But in any case, I've just now found the root of the problem, that is not in any ways related to redmine.
In fact, I had an old global alias defined by dokuwiki (in /etc/apache2/conf.d), which prevented redmine users to access redmine's /wiki path.
