#17174: WordPress 3.1.1 breaks date archive filtering by tag or category

 Prior to WP 3.1.1, I used to be able to filter my blog's yearly and
 monthly archives by tag or category, using a URL like the following:

 http://www.myblog.com/2011/?tag=sometag

 or

 http://www.myblog.com/2011/04/?category=somecategory

 After upgrading to 3.1.1 from 3.1, when I try to visit such a URL, I get
 redirected to the page for the tag or category archive, like
 http://www.myblog.com/tag/sometag

 This is very annoying. I appreciated being able to filter my archives and
 link to the kind of URLs depicted above so I could show only posts
 matching a particular tag or category *and* a date range.

 I have successfully reproduced this issue on multiple WordPress
 installations running 3.1.1. The issue persists even when I switch to the
 default permalink structure, though I see different symptoms.

 I cannot reproduce the issue in a 3.1 installation, which leads me to
 conclude the problem is a byproduct of the fixes introduced in 3.1.1.
