I think there's a possibility that you hit the new bug in 6.7 and the error propagated to the filesystem so that now it's detectable on any lower version too. We have only indirect evidence here, 2 reports of the page reference counts and all in a short window after 6.7. The lack of other reports would point out to either one time damage or some other factor like hardware problems.
