I got this crash log while querying an array of managed object, however, while running in the simulator it does not happen. Even in the device, sometimes it happens, sometimes not. Someone can explain to me why and what is the error?

This is the line where 47 of the error:
for (Item *item in model.items)
Notice that the Item is a Core Data object, and model is the class which contains a NSArray of type Item items, this class is populated with items when the NSXML Parser goes through each downloaded data, whenever it finishes parsing one element, it creates one Item object and saves into the Core Data context. Three20 is used in my project.
As a general rule of thumb, most crashes that happen on the device only result from some issue with the drive. (Especially if it obviously doesn't involve any other device specific function such as the accelerometer.) The most likely cause is a full drive. All kinds of weird things start happening when the disk gets full.
In this crash, Core Data is attempting to load the attributes of a fault (ghost) object and failing. This can happen when a cache gets out of synch with the store or if you have otherwise create a condition in which the store is altered without the knowledge of the context.
(1) I would start by seeing if the device is full and freeing up some room if it is. Conversely, you could intentionally fill the drive to try and trigger the error consistently.
(2) If you have multiple context, make sure they don't manipulate the same objects at the same time.
Edit:
The error could be caused by the object returned from the model.items not actually being of class "Item" it could be a superclass that lacks the attribute. That would explain why it fails when it tries to fault in (read in) the actual attribute.
Just a guess. Not sure why that would only occur on the device. Is there networking involved here?
More code from around the point of failure might be helpful.
I'm surprised the exception being raised isn't printed. There isn't a lot of evidence to work with here.
In any case, the most likely cause of this is not correctly using threads with Core Data. That is, do you have multiple threads and, if so, are you sure you are properly managing your managed object context(s) across the threads?
