 * See also my response to your other post.
    I can’t reproduce this error: nor in
   my webserver logfiles, nor in WP itself with debug activated.

 * Btw, since it seems to have something to do with attributes (in your case): can
   you provide an example of the attribute value and the possible default value 
   that triggers this error?

 * Ok, I figured it out. It’s a prob in the preg_quote function I used, I forgot
   to also quote “/”.
    So fixed here: [http://plugins.trac.wordpress.org/changeset/828612](http://plugins.trac.wordpress.org/changeset/828612)
