Hi all,
I'm seeing crash reports from a small percentage of my users with this exception on startup:
System.Windows.Markup.XamlParseException: Set property 'System.Windows.FrameworkElement.Style' threw an exception. ---> System.InvalidOperationException:
The sum of AccelerationRatio and DecelerationRatio must be less than or equal to one.

The problem is I'm unable to reproduce the crash, and I can't figure out where it is actually happening from the stack trace.
Can someone tell me how I would go about troubleshooting this issue with the user so I can narrow down what needs fixing?
