EVALUATION There have been several CMS bugs fixed since the version on which these failures are reported, so this data is by now obsolete. I'd suggest checking with the customer if there is still an issue with a much more recent update release and i'd be inclined to otherwise close this bug as "not reproducible". I'll mark this "incomplete" so submitter is pinged for recent status, and will close if no updates are available from customer (under the dictum that no news is good news).
