CoreData crash on dealloc

Subject: CoreData crash on dealloc

I have a CoreData app that sometimes crashes on exit. It only happens occasionally. There was a question about this on the list in January, but there was no solution posted. It looks as if it is happening in a release of an autorelease pool. Anyone have this problem before?

 This is the stack trace:

Exception:  EXC_BAD_ACCESS (0x0001)
Codes:      KERN_INVALID_ADDRESS (0x0001) at 0x50616e65
