This here is an absolutely serious issue/bug report: As soon as I switch on the doctype-checkbox under/below "Output an XHTML+RDFa DOCTYPE:" on "/admin/settings/rdf", I get -- in the dblog/ex-watchdog module -- an endless row of the error message below:

- mysqli_real_escape_string() expects parameter 1 to be mysqli, null given in /linux-directory/httpd/websites/example.com/includes/database.mysqli.inc in Zeile 323.
- [...]

I also get these errors as soon as the RDF module is enabled.

I received a similar error, when I enabled the RDFa namespaces. The details of the error output are similar to the following:

Type	php
Date	Monday, April 12, 2010 - 10:35
User	Visitor
Location	http://www.pagevisions.com/admin/settings
Referrer	http://www.pagevisions.com/admin/build
Message	mysqli_query() expects parameter 1 to be mysqli, null given in /home/monica1205/pagevisions.com/includes/database.mysqli.inc on line 108.
Severity	error
Hostname	75.230.228.252
Operations

A key to the error is that I was actually running as the id 1, and not an anonymous visitor.

The backtrace from the Trace module for one of the errors is:

Same here when I enable "Output an XHTML+RDFa DOCTYPE: " I begin to get this error on pages, regardless of permission level.

mysqli_real_escape_string() expects parameter 1 to be mysqli, null given in database.mysqli.inc on line 323

I am using RDF module 1.0-alpha-7 with Drupal 6.17.
I am also using the RDF/XML format
I am also storing 1 local repository.

Don't know if this helps, hopefully we can find a commonality within our situations.
