This issue may be related to Bug #1012721 somehow, which I reported earlier.
Try starting Midori with

  midori -a http://web-site-address

If it makes Midori work normal (with low CPU usage), this is the case.
Regards,
  Vladimir

Hi. Thanks for your reply.
I got an error when doing midori -a http://web-site-address in PC-BSD
terminal emulator.

ERROR:/usr/ports/www/midori/work/midori-0.4.7/katze/midori-paths.vala:117:midori_paths_get_user_data_dir:

Well, I have something similar lately. In such case you may be interested in following this bug report as well: https://bugs.gentoo.org/show_bug.cgi?id=435846

It do not know/ why midori also increases Xorg's WCPU usage
