Comment(by gaobo):

 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.

 Replying to [comment:11 ryan]:
 > I can reproduce this in 2.9.2 as well. When importing posts, the
 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><![CDATA[远征手记]]></category>
 > }}}
 >
 > This field should be used:
 >
 > {{{
 > <category domain="category"
 nicename="eternity"><![CDATA[远征手记]]></category>
 > }}}
 >
 > And we should use the nicename as the slug when calling get_term_by() in
 the categories loop of process_post().
 >
 > Since the importer is now in the plugins repo, this is not a blocker for
 3.0 release. Fixing it would be very nice however.  Anyone want to have a
 try?
