Mystery WPF problem that I need help with…

I didn’t want to do this so early in the life of this site but I’m at a loss of what to do. We’ve got a heavy WPF application which has a nice little animated progress spinner on it using WPF animation (DoubleAnimation). The problem is basically laid out here: http://social.msdn.microsoft.com/Forums/en-US/wpf/thread/a4b2df90-8fa3-4b59-9242-9c48000fa62a. As you can see, there’s no answers yet and it’s been out there since March. We are seeing this randomly occur in our application and I have identified the source POSSIBLY being the progress spinner’s infinite animation (we turned the animation off and don’t see the problem again… yet).

Here’s our stacktrace. As you can see there, is not specific source to OUR code… it’s all WPF internals… and this happens completely randomly at random intervals and is not reproduceable on some machines. I appreciate any help that can be provided.

EDIT: Just wanted to update everyone on how we minimized this issue. From the MSDN forums, the only common link we could find is our development machine hardware/software. The only conclusion we could come up with is a WPF incompatibility between our hardware and/or software. We added an app settings flag that is checked before any infinite animations are executed and that flag is set to true to disable the animations on our development machines but set to false during deployment. This gives us access to enable/disable this feature if we ever see it occur on client computers (which we hope does not happen!).
