I found a minor bug that affects closed beta proposals from Area51. *
If you look at the list of users for such a proposal, you'll see that the flair includes a broken image link:
The source for these is just an empty
img tag, since obviously the beta's image was taken offline again:
So, probably a minor thing to fix by just removing the tag altogether.
* sorry, couldn't come up with an internal search as I'm not used to how Area51 works.
