I guess the issue must have been seen with Trac 1.0.10 because it was released on 2016-02-20, and I'm pretty sure I upgraded trac-hacks.org immediately. However, I can't reproduce by navigating to /query?status=closed&component=DoxygenPlugin&type=enhancement&group=resolution&max=0&desc=1&order=id.

Replying to Ryan J Ollos:

I don't see any html-entity presentation of & elsewhere in Trac bug reports, so I guess the path was as presented: /query?status=closed&component=DoxygenPlugin&type=enhancement&group=resolution&max=0&desc=1&order=id.
