16662	Permalinks not working with 'category'	Ipstenu		"Okay, there are a handful of people, MOSTLY on IIS, who are having permalinks problems.

Basically categories don't work. They're finding out when they use /%category%/%postname%/ for permalinks.  If they use default (ugly) URLs, it's fine.  If they use pretty permalinks with /%year%/%month%/%day%/%postname%/ the post URLs work but the category ones do not.

I can't reproduce it, but so far I've noted

If they use IIS, this often fixes it
http://wordpress.org/extend/plugins/permalink-fix-disable-canonical-redirects-pack/

It manifest as EITHER 404s OR a refresh-loop.

I'm not sure if it's really a bug or not, and since I can't reproduce it, I'm gonna list the slew of posts with this problem.  Yes, they've tested with the default themes, and that doesn't help.
