Good point - if pages have different content but you use the same title, then that heads you toward keyword cannibalization. Different urls for the same content also gives you duplicate urls (naturally) but it's not the same issue. WMT will report it either way - it's up to you to intangle the two.

With pagination, you do have different content under potentially the same title - and the question is do you need to differentiate those titles? Do you want all those pages indexed? The can't all rank for the keywords in the title, so to really do right by those deeper pages in the pagination set, how will you handle it?
