Bug in textpattern import

[jhernandis]

In "textpattern.php" in wp-admin/import, at the line 332, shows like this:

				$cats = array();
				$category1 = get_category_by_slug($Category1);
				$category1 = $category1->term_id;
				$category2 = get_category_by_slug($Category2);
				$category2 = $category1->term_id;
				if($cat1 = $category1) { $cats[1] = $cat1; }
				if($cat2 = $category2) { $cats[2] = $cat2; }

There is a bug that makes the categories was not assigned correctly. The right code is that:

				$cats = array();
				$category1 = get_category_by_slug($Category1);
				$category1 = $category1->term_id;
				$category2 = get_category_by_slug($Category2);
				$category2 = $category2->term_id;
				if($cat1 = $category1) { $cats[0] = $cat1; }
				if($cat2 = $category2) { $cats[1] = $cat2; }
