Comment (by SergeyBiryukov):

 I see some reports that http://example.com/uncategorized/ (without the
 category base) no longer works, which was previously mentioned in #19876
 as a collateral effect.

 Steps to reproduce:
 1. Set permalink structure to `/%category%/%postname%.html`.
 2. Install [http://wordpress.org/extend/plugins/remove-parents/ Remove
 Parents] (outdated, but apparently still used) or similar plugin that
 removes `/category` prefix directly from links, without touching rewrite
 rules.
 3. Visit http://example.com/uncategorized/.

 In 3.3, a category archive is displayed. In 3.4, you get a 404 error.

 Confirmed that [attachment:21020.diff] fixes the issue.
