Comment 1 for bug 393359

I am having the exactly same problem here.
Adding some information I think might be useful:
I am moving from Mozilla Thunderbird to Evolution. I added all my RSS feeds to the plugin configurations and I was able to refresh all of them. The one wich requires authorization asked for name and password and I checked the box for remembering them later. Well, so far, so good, I was able to get the first messages. Then, later, when I clicked the button to update my feeds I notice a message saying that authorization has failed and the only feed that requires authorization did not update.
I removed that feed and tried adding it again, then the above problem appeared.
