I added a new ticket with patch last night:
http://trac.wordpress.org/ticket/7707
There is a bug in the duplicate post detection of the WordPress WXR
importer. The creation of postmeta occurs outside of the if branch which
detects whether a post is a duplicate. I assume that this is in order to
attach additional metadata to the copy of the post already in the
database (which could be due to re-starting a previously interrupted
import). However, due to the way the code is structured, the $post_id
variable is not set in this case, and so the postmeta entries are
assigned to post_id=0 (zero).
The solution is to capture the post_id returned from the post_exists()
function, and set the $post_id variable in the other branch of the
duplicate post test.
The orphaned postmeta becomes a problem the next time you go to create a
new post.
