So, given that this is something people (or at least the one who responded) think ought to work -- is this something we ought to be testing regularly? If we're planning to upgrade users from 1.0.1 to 1.2, 1.1 to 1.2, or 1.0.1 to 1.1 to 1.2, should we be testing those upgrade paths to make sure they work properly? (Or are we testing them, and my problem was an edge case resulting from having started a little bit before the 1.0.1 release?) I'd note that testing upgrade paths requires more than cursory testing; it requires testing the functionality of applications (for example, that an email account or calendar account configured in 1.0.1 still works correctly in 1.2). -David -- 𝄞 L.
