I noticed this problem while doing some manual testing after landing
http://codereview.chromium.org/8727024/

FYI, elvin is also working on a sync integration test at
http://codereview.chromium.org/8735019/ which we can likely eventually use to
test this in another way as well.

Try job failure for 8774011-1 on win_rel for step "update".
http://build.chromium.org/p/tryserver.chromium/buildstatus?builder=win_rel&nu...

Step "update" is always a major failure.
Look at the try server FAQ for more details.
