Pass invalid array to _menu_load_objects

I created a page with arguments using views and got the error described in http://drupal.org/node/308206
Then I took the steps there to fix it.
I assume this is a bug in views. The view I created pulled all blog posts using a url: blog/%/%/% where
%1 = user
%2 = year
%3 = month
This happened with both rc1 and rc2. Of course, it's also possible that I am doing something wrong...
