AIR 3.1.0 crashing in webkit.dll on Windows XP

We have a customer who uses an Adobe AIR application we wrote. They have been on 2.7 of AIR for sometime and our application has run fine, 24 hours a day, 7 days a week. AIR 3.1.0 was released and now, only on the Windows XP machines, the application is crashing routinely on a fault in webkit.dll. We have seen no such problem on the Windows 7 machines. I have included a screenshot from the Event Viewer in Windows XP. The customer was able to uninstall 3.1.0 and put back AIR 2.7 and the problems went away. Has anyone else experienced a similar problem?
