UIImagePickerController Shuts Down on Memory Warnings

Question

I'm getting a memory warning when opening a UIImagePickerController. Since I upgraded to iOS 4.01 this memory warning happens more often but the drastic change in behavior is:

The UIImagePickerController's automatic response to the memory warning, since upgrading to 4.01, is to run its close shutter animation and stall there, with the closed shutter on screen.

I could dismiss the UIImagePickerController from the parent ViewController in the didReceiveMemoryWarning method, but that would make for a bad user experience.

Has anyone seen this problem? Is there a way to handle the memory warning so that the UIImagePickerController doesn't shut itself down?
