Comment (by nacin):

 You'll want to remove `return apply_filters( 'sanitize_html_class',
 $sanitized, $class, $fallback );`, otherwise you'll create an indefinite
 loop.

 So change that to `return $sanitized;`

 Also, you need to check out the order in which things are passed. The
 filter passes $sanitized, then $class, then $fallback. So:

 `function my_sanitize_html_class( $class, $fallback = '' ) {`

 Needs to be:

 `function my_sanitize_html_class( $sanitize, $class, $fallback ) {`

 Additionally, you need all three arguments, so:

 `add_filter( 'sanitize_html_class', 'my_sanitize_html_class', 10, 3 );

 Note that 10 is priority. 10 is default.
