Hi Ben-
If you are using a custom class to represent an entity in your model,
you must make sure that it is a subclass of NSManagedObject in your
code (and not NSObject). This might not be your issue, but I have had
this bite me before - it issues the same error with no exception
thrown, and is quite a challenge to debug. I fall into this when
moving fast in model creation, as the template for adding an Objective-
C Class to a project makes it a subclass of NSObject.
Hope this helps!

Hi all:
I've been making some changes to one of my apps which include a
change to the data model. Now whenever I start up the app it
crashes (EXEC_BAD_ACCESS) in
addPersistentStoreWithType:configuration:URL:options:error:. I've
factored out all the passed arguments and it's still crashing. I
figure it must have to do with the change in the model, but I can't
see why that would make it crash and not report an error or trow an
exception, particularly if the URL points to a nonexistent
file )e.g. it will create a new store file). Any thoughts?
Thanks,
->Ben
