Temporary solution:

Id suggest another possible fix for WP 3.3.1.
Open qtranslate/qtranslate_wphacks.php file, find line 77.
And replace this:
if(‘html’ != wp_default_editor()) {
remove_filter(‘the_editor_content’, ‘wp_richedit_pre’);
}
WITH:
$version = (float) get_bloginfo( ‘version’ );
if ( $version < 3.3 ) {
if(‘html’ != wp_default_editor()) {
remove_filter(‘the_editor_content’, ‘wp_richedit_pre’);
}
}
