Changes (by gaobo):

  * milestone:  WordPress.org site => 3.0


Comment:

 The situation is more serious than it looks like. Importer seems to have
 been moved into WordPress.org site as a plug-in, but it turns out to be an
 essential part of WordPress 3.0 (or any future release). For WordPress
 3.0, many people will perform the import action and it affects there user
 experience badly.

 So, ryan or any buddies there, you have already found the root cause of
 the problem. So please take a few steps to have it resolved. I conducted a
 survey among my Chinese and Japanese friends, and 17 out of 20 of them
 complained about this issue. It shows a clear fact: THIS PROBLEM HURTS.

 Let's work together to remove this tiny but important road blocker before
 shipping WordPress 3.0, thanks for all your time and efforts.

 > I suppose this to be a relatively important bug, since the first thing
 people usually do after deployment of 3.0 is to import their content from
 previous blogs as I did, and that's why I recognized the existence of the
 bug. However I agree that since the importer part has been moved into
 WORDPRESS.ORG we can move on and change its milestone, but having it fixed
 can provide many users of 3.0 with a better experience.

 category slug is not being referenced when checking to see if the category
 exists.  This ends up in the category being recreated with a new slug.
 Instead of using this field:

 > > }}}

 > > <category domain="category"
 nicename="eternity"><![CDATA[远征手记]]></category>
 > > }}}

 in the categories loop of process_post().

 for 3.0 release. Fixing it would be very nice however.  Anyone want to
 have a try?
