Well, I'm the one who posted about this on enwiki, and was told in no 
uncertain terms by Tim Starling that it's the API's fault, not the 
database's.

The problem is that if the invalid title retrieved from one query is used in 
the titles= parameter of another query, the API returns a Bad Title error on 
the entire query (even if there are 50 titles |'ed together).  Some possible 
solutions to this, in no particular order:

1)  delete the damn page entry from the database
2)  change the API so that, if there is a bad title in the titles= 
parameter, it still returns the query result for all the valid titles.
3)  change the API so that it doesn't return the invalid page entry in the 
first place (probably not such a good idea, now that I think about it)
