hi,

i also had/have the same problem.

i reviewed the method you mentioned but couldn't identify any bug?
can you tell me where you suppose one?

in my test pagination sometimes reloaded/looped after first page/items, but sometimes also after more/x-pages.

as the problem today doesn't occur, I guess the cause might be more related to caching at some level?
the error first occurred after removing some old feed items, maybe this results in inconsistency to cached data?
