If you go to http://www.flickr.com/activity and scroll down their is a link to an RSS feed. Looks like this:
http://api.flickr.com/services/feeds/...
In my case the URL is readable by Firefox for example but when I try and subscribe via the newsblur web interface I get the error "This address does not point to an RSS feed or a website with an RSS feed.". I also get a popup list that suggests other people's flickr feeds (for uploads, comments, etc.).

Do you mean that Newsblur is treating %2b as a urlencoded + sign (i.e. a space)? How can I work around that, by further percent encoding the percent encoded plus ?
tried that, didn't work.

Somebody somewhere is double encoding, but I don't think it's NewsBlur. You just need to pass the raw URL, but Flickr might be encoding it for display.
So, there was indeed something suspicious about the URL:
When hovering over the link on the flickr page I see a URL which has unencoded special characters, specifically @, + and =. When copying or clicking this link in Firefox my clipboard or address bar respectively contains the URL with only the plus and the equals sign percent encoded.
With this I thought that I had found the problem, however even if I encode the @ sign as %40 so that the URL query args are properly encoded still Newsblur doesn't accept the URL. Loading the URL in Firefox or in Chrome brings up the RSS document as expected.

Another thing that is suspicious, and happens only in Firefox, not in Chrome, is the following: after copying the RSS url from the address bar I go to Newsblur and click on the button in the lower left to add a new feed (+). The popup shows up and he text input element is focused so I can just press Control-V on my keyboard to paste the feed URL. After half a second a list of feeds of appears above the text input element. Nothing else happens but the minute I move my mouse pointer even slightly the URL in the text input element is substituted with another URL from the feed list, with the corresponding list entry getting highlighted. This happens despite the fact that the pointer doesn't go near the list.
Here's what I see before and after I move the pointer:
