The collected information list (/infocollector/overview) shows several empty items under certain conditions. In my case, I have 34 items with collected information, this corresponds with the output from "select count from ezinfocollection group by ezinfocollection.contentobject_id;"

If I select 50 items per page, all is OK. At 25 items per page, page 1 is OK, page 2 contains 25 empty items, in addition to the 9 items that are correctly shown. See screenshot. At 10 items per page, page 1 is OK, page 2 contains 10 empty items + 10 correct ones, page 3 contains 20 empty items + 10 correct ones, page 4 contains 30 empty items + 4 correct ones. So there is a clear pattern here.

The empty items have no name, and no ID. In the link to the right (/infocollector/collectionlist/XXX) XXX is missing for the empty items. The number of collections in that link is 681 for all the empty items. Interestingly, this is the same number as "select count from ezinfocollection;".

Steps to reproduce

See description.
Items per page must be less than the total amount of items with collected information.
