2.6 expire doesn't cope properly with articles having multiple groups. It tries to make the appropriate links to a single file, but if one of the directories doesn't exist it tries to mkdir the wrong directory. An item sent to "net.general,net.news.newsite" was the first item in net.news.newsite to expire; the link failed because net.news.newsite didn't exist, and expire tried to mkdir net.general again!
