DotClear Importer plugin with WP 3.0 RC

I would like to import my Dotclear database in WordPress.
I’ve installed WordPress 3.0 Release Candidate without problem.
I’ve installed DotClear Importer plugin Version 0.2 through the WP admin.
I’ve clicked on tools/import and selected Dotclear, then I’ve completed my database info. That’s ok with that.
then the following messages are displayed :

Done! 0 categories imported.
Done! 2 users imported.
Done! 0 posts imported.
Done! 4770 comments imported.
Done! 0 links or link categories imported.

what to know :
Server : OVH
my Dotclear version is 2.2 alpha1 r2949.
this is a multi-blog with 2 blog_id (default and life).
wordpress and dotclear are on the same database.
dotclear tables are prefixed by dc_ and wordpress tables by wp_.
the comments are imported in wp_comments table with a 0 in the comment_post_ID.
that’s ok for the imported users.

Thanks for your help
