weird brid.gy author URLs

For a while, I’ve noticed that brid.gy was providing profiles.google.com URLs for authors for some Google+ activities. Today, I dug into it a little and discovered that it’s only doing this for +1s; Google+ reshares have the expected plus.google.com author URLs. For example, compare the links on the two rows of faces in the “Likes and Reposts” of this post.

Next I looked at the markup brid.gy generates for these webmentions. Compare an example +1 versus an example reshare. The +1 contains the following snippet:

<div class="h-card p-author">
  <div class="p-name">
    <a class="u-url" href="https://profiles.google.com/105078911987805797425"
      >Cristian Gary Bufadel</a
    >
  </div>
  <a class="u-url" href="https://plus.google.com/105078911987805797425"></a>
</div>

The author h-card contains two URLs, one with profiles.google.com and one with plus.google.com. And the latter has no link text, it’s just empty.

This certainly looks like a bug. I glanced at the brid.gy code briefly, but didn’t immediately find the culprit. Ryan, you have any thoughts?
