Do you mind trying updating to r206713 then r206714 then r206717 then r206819 and r206834? Or start with r206717 and go earlier or later based on whether it works. If you can figure out what commit was at fault, I'll be glad to work with you to isolate whatever's responsible. In the meantime, I'll try to reproduce and fix this locally. Thanks, Juli.
