Sundog,
Both of those plugins have been tested with Joomla 1.7. Kunena with the 1.6.5 version your using, and JomSocial with 2.2.3 and 2.2.4. So.. it should work.
If you could, please try disabling just one of the plugins and see if it works. If so, swap the one that's enabled, and try again. If you can help narrow it down that way, it will help us a bit. If you're really overzealous, when you find the 'problem' plugin, try enabling it but disabling some of the features (avatar import, etc) to narrow down if there's a specific setting causing the problem.
Thanks,
Alex
