404 anomaly

Please refer to attached PNG.
I am the only one committing to the repository in question, though I do so from two different machines. I use the same ssh credentials for both. For some reason the commits are listed on my Newsfeed page as being from "Anonymous". However, when I click the link next to each individual commit, it's associated correctly with me. On the Newsfeed page, when I click on the "Anonymous" link, to see who Anonymous is, I get a 404.
