[Mediawiki-l] Error trying to upgrade from 1.15.1 to 1.16.0

[Michael Eshom]

  I am trying to upgrade from MediaWiki 1.15.1 to MediaWiki 1.16.0, but 
when I run the upgrade file, I just get an error:

Fatal error: Call to a member function getDbType() on a non-object in /.../wiki/maintenance/doMaintenance.php on line 79


I have Apache 2.2.16, PHP 5.3.3 and MySQL 5.1.48 running on CentOS 5.5.

I can provide a list of extensions if necessary.
