[Mediawiki-l] db error messages

[a@kid]

I haven't set $wgShowSQLErrors in LocalSettings.php and yet i am  
still getting mysql error messages. Sometimes these include the name  
of the database and the db user, other times they include a Backtrace  
of the error.

I need to investigate further, but the error messages may be only  
coming from my own custom Special Pages.
