The OpenLayers server threw a disk, and clobbered another, resulting in a loss

of data up to our last backup. In the previous subversion repository, this was
r1694->r1777. I'm sorry to all those of you who might have checked out that 
code, as this will surely cause problems for you. We're currently working to
figure out what went wrong, and how to prevent it in the future.
