Comment (by sivel):

 I haven't tried any of the plugins referenced to have issues but did
 create a test plugin that successfully removes that filter and adds a new
 filter without issue.

 When I get a chance I will try to test.  however, looking at what those 2
 plugins do, leads me to believe it was likely the addition of the
 following code in sanitize_title and has nothing to do with the filter

     if ( 'save' == $context )
         $title = remove_accents($title);

 A work around may be to do something like:

 remove_filter( 'sanitize_title', 'sanitize_title_with_dashes');
 add_filter( 'sanitize_title', 'restore_raw_title', 9, 3 );
 function restore_raw_title( $title, $raw_title, $context ) {
     if ( $context == 'save' )
         return $raw_title;
         return $title;

 And then go about adding your own filter at priority 10 or higher to
 filter sanitize_title the way you want.
