Two-three weeks ago I unsubscribed of all feeds due to this issue. Even putting auto-update to manual was not solving it for me. Today I decided to add one feed(it is usually empty or contains 1-2 items), configured to auto update on 3 hours. After a while I noticed the Transfers arrow in status bar. When opened status menu to my surprise there was indication of 5 feeds updating! I left it like and it was stuck for a good hour. Then I manually cancelled the transfer. So may be this bug is more complex or there are several separate issues with identical result - feeds stuck in updating status infinitely.
