change this to:

	from AppKit import NSTableDataSource
	class entityTable(NSTableDataSource):

PyObjc needs to know the method signatures (parameter and return 
types). If it doesn't know them it assumes they are of type ID, which 
causes the crash.

The NSTableDataSource class declares the proper method signatures 
signatures for you.
