Comment pagers in D7: They appear even when the page has only 1 comment!
After researching for quite some time, I´ve found this reply in the Omega issue queue that gave me the answer. Even when the answer has nothing to do with the theme layer.

In short: When this happens to you, it´s probably because the pager is conflicting with a views block with it´s own pager activated, all in the same page.

You actually fix this by giving the Views pager a different value than the default zero.

Posted it here just in case anyone encounters with this issue again!
