Default Tableview - deleting sections

My application contains a table view with rows and sections.
When I delete the last item of a section, I delete the section. It works fine.
But, when i move the last row of a section into another section, I get an error.

Here is my code in both cases :

[categoryArray removeObjectAtIndex:indexPath.section];
[tableView deleteSections:[NSIndexSet indexSetWithIndex:indexPath.section] withRowAnimation:UITableViewRowAnimationTop];

Here is the error that occurs in moveRowAtIndexPath:fromIndexPath:toIndexPath:

2009-03-11 17:56:09.524 Test[5140:20b] 1
2009-03-11 17:56:09.525 Test[5140:20b] *** Terminating app due to uncaught exception 'NSRangeException', reason: '*** -[NSCFArray objectAtIndex:]: index (5) beyond bounds (5)'

Any help would be great !

I had this issue and I just solved it. In my case, I was using Core Data, and I had to wrap the deletion logic in 

    [tableView beginUpdates];
    ...
    [tableView endUpdates];

I had to wrap everything; from before I deleted the data/section until after I had saved the context. Hope it helps.

Well, in fact, my code isn't trying to access to an element. I think the error come from a UITableView method (that I don't know because we only have access to header files of the sdk). The problem occurs at this point :

[tableView deleteSections:[NSIndexSet indexSetWithIndex:fromIndexPath.section] withRowAnimation:UITableViewRowAnimationTop];

It looks like you are trying to access the sixth element of a five-element array. Are you using the array size as the index without subtracting 1?
