Random problems with rss and atom feeds

Sometimes, the rss and/or atom feed is broken with errors like this

---

This page contains the following errors:

error on line 22 at column 51: error parsing attribute name Below is a rendering of the page up to the first error.

[....] Author list:

I am not sure what the root problem is and how to debug it. If you give me some pointers to debug it I can provide more information.

To clarify, the above output is from the /atom service

By looking the webpage source it appears that Authors are meant to be listed as

Name <email>

Could the <email> part confuse the xml and treats the <email> as an attribute?

Modifying the

Author list: <b>{{ b.responsible_users|join(', ') }}</b><br/>

to be

Author list: <b>{{ b.responsible_users|join(', ')|e }}</b><br/>

in ​https://github.com/buildbot/buildbot/blob/master/master/buildbot/status/web/templates/feed_description.html

seems to fixes the problem because now the output is generated as

Name &lt;email&gt;
