es:Special:Brokneredirects (updated as today) shows a list of "broken" redirects to existing pages in the new namespace (bug 9304)
Doing a fast sample, it seems like those pages were moved (ie. the redirect was created) before activating the new namespace. Maybe some links table wasn't properly updated?
See also bug 7890. A shell user should probably look.
links refresh is needed, i'll run it later.
