So, I think I figured it out and I'll leave what I found here to help others.
This issue appears to be that whenever I have the default display units (under settings tab in the back office) set to days instead of posts, this behavior happens. I set the unit back to posts and now I can browse posts through the admin interface.
I'm guessing this does belong in the bugs for 1.6 forum. I have no strong preference for either setting, so I'm happy with posts as the main unit.
