This is new on the trunk. It's not a significant volume but it's a regression. We don't have high number of users. It started to show up on 02/04. Can someone take a look and see if it's something that seems obvious. Adding Johnny and Dmandelin - add someone else if you are the wrong guys.

I believe there's a fix for this in bug 631488. Duping.
