On the toolserver, the pagelinks table contains lots'o'links to a blank target:
select * from pagelinks where pl_title="" limit 100 ;
(tried up to limit 10000, found 10000 but sloooow)
Apparently, many links to empty page titles in namespace 0. This
surfaced when one of my tools spat out blank results. It wasn't there
a few weeks ago (two month at most). Tested for en and de wikipedia.
Is this a toolserver replication thing, or are these things in the
live database as well? It's probably not a showstopper, but we might
want to get rid of both links and bug anyway.
