Exception closing NSPersistentDocument with unsaved data

Hi all,

I am writing CoreData document based app. When I close
the document with unsaved changes, this exception is
thrown:

[NSAutoreleasePool dealloc]: Exception ignored while
releasing an object in an autorelease pool: The
NSManagedObject with ID:0x34bf20
<x-coredata:///DataTableDesc/t1849B01E-C3A3-46B5-9FB6-3AB954EB1BE9>
has been invalidated.

Exception does not happen if content of the document
is saved prior to closing.

Any hints?
Thanks in advance and happy Christmass,

Gorazd
