Upon further review buddypress is actually causing this same thing to happen to all my theme options. (using Atahualpa)

I don’t know what exactly it is. I just know if the buddypress plugin is enabled, nav-menu.php doesn’t work. I have to turn off buddypress so I can edit my menu, then enable it again.

I have not, I installed 1.9.2, thru the plugin installer inside WordPress. Might that newer version help then?
