BUG: Can't browse pages when the thread list has certain filters on

[Vanden]

If I go to the Sort By menu in the top-right of the thread list in a forum category, choose Custom, and set the Filter to "Topics I've Posted In," the page numbers in the top and bottom of the thread list disappear, and it's impossible to see any results that don't show up on the first page. This doesn't seem to affect the other filter options; if there's enough threads to fill multiple pages when the Filter is set to "Topics I Started" instead, the page numbers are still there, and it's possible to view all results.
