It was already flawed in R10.04.
If you click on the Gizmos node, the pagination page shows 3 pages when there should be only 2 and if you get to the page 3 it crashes.
If you come from the breadcrumb the problem is the same.
On the other hand, from R11.04 there is a "Popular Categories" section at top of the main screen, and from there it works correctly.
But in this version the "Featured Products" pagination shows the same symptom than the category pagination.
The "Featured Products" pagination works almost correctly from R12.04, but shows 2 pages when the second is useless and empty, at least no crashes!
