[wp-testers] Importing from 2.9 version

[Andrew Nacin]

Could you check to see if you are running a database drop-in? If the drop-in
is extending the wpdb class but using it's _real_escape() method improperly,
that could cause this.

Two ways to check:
1. Check if you have a file at wp-content/db.php
2. Or, new in 3.0, go to Plugins > Installed. If you have a "Drop-ins"
filter at the top of the page, check that to see if you're running a db.php
file. (If no "Drop-ins" submenu, then no db.php file.)

This can also be caused by a plugin using one of the database methods
improperly.
