Here are the versions I am running.
Also, further development, when enabling sqlite, I get "driver not found", though I assume that is a server configuration on my end.

PHP 5.3.22-1~dotdeb.0 (fpm-fcgi) (built: Mar 3 2013 00:11:39)
php5-sqlite (5.3.22-1~dotdeb.0)
php5-mysql (5.3.22-1~dotdeb.0)
nginx (1.2.7-1~dotdeb.1)

Let me know if I can give you any more information that would aid in troubleshooting.
