I'm not sure what's going on here but in addition to just crashing (now going on a hundred times in the last day or two alone), the version history seems to be broken.

Becasue of all of the crashing, I've been saving versions roughly every 30s to couple of minutes but (a) many of those aren't appearing in the version history list, (b) the last hour or two of versions are gone and (c) things that are an hour or two old are being listed as a few minutes ago.
