 * After a lot of swearing through gritted teeth I discovered that, much like the
   reserved term issue that results in a 404 error (‘page not found’) when processing
   a form:

 * [http://wordpress.org/support/topic/contact-form-404-error](http://wordpress.org/support/topic/contact-form-404-error)
 * the same thing happens when using custom taxonomies. In my case the problem was
   the `<select name="taxonomy">` I was using for a drop-down. Change it to `<select
   name="get_taxonomy">` and the form now processes properly.
