Adding "Instructions on how to ask questions" leads to server errors.

edit

I've just been trying to add a snippet to the "Instructions on how to ask questions" setting. I validated the snippet, and it's correct:

<h2>How do I ask a good question?</h2>
Good questions are easy to find, and should have enough information for someone to suggest a solution. Here are some tips on asking good questions:

<ul>
<li>Frame a question</li>
<li>Use correct tags. See the <a href="ask.stg.fedoraproject.org/tags">list of tags</a> for what tags you should use. It makes it easy for people to find your question</li>
<li>Use the mark up tools: This makes your question more readable</li>
<li>Provide information that could be helpful to a reader</li>
</ul>

A complete list of tips is maintained on our <a href="https://fedoraproject.org/wiki/Ask_fedora_guidelines#List">guidelines page</a>. Please do read it through at least once.

When I click the "save" button, the server barfs with an internal error. Here's the httpd error log snippet:
