P: Lightroom sometimes changes orientation inadvertently

I've had this happen a few times since Lr3.4RC (or at least I don't recall it happening with previous versions) - I thought it was me, but this time all I did was click a thumbnail and it switched from portrait to landscape orientation.

    This is a bug (since 1.0, actually, though for many folks it's rare) and this reminds me to pull it out of deferral. It requires a data model change, so it keeps getting forgotten until too late in the cycle. Basically, in order to deal with external edits correctly, LR re-reads certain metadata (including orientation) if it detects a modification date change. So if the mod time changes by more than a certain amount and the orientation hasn't been saved back into metadata, it'll re-read and revert.

    There are a number of ways the mod time can get accidentally tweaked that can trigger this behavior.
