Closed topics and RSS feeds

I don’t know if this is a RSS bug or in a topic display, but today I’ve stopped to allow topics in some blogs that are visible in RSS feeds.

For example, I see in the RSS reader this one www.habrahabr.ru/blog/i_am_clever/10405.html
or this one
www.habrahabr.ru/blog/humour/10406.html
topic, I can read them there, but when I click on the link I get

“Oops!
')
By chance and by the administrators of this blog, you cannot see this habratopic. ”

If I do not have access to this blog, it is quite logical, IMHO, if I cannot see them by RSS. And vice versa.
