The actual issue I see with that callback is that you are not defining the args signature correctly and its actually failing. When you use that specific callback, it wants to also pass a second parameter for the optionally provided userdata when the callback was registered.
This example works for me. import maya.OpenMaya as om import maya.cmds as mc def function(retCode, userData=None): om.MScriptUtil.setBool(retCode, False) return retCode cbk_id = om.MSceneMessage.addCheckCallback( om.MSceneMessage.kBeforeSaveCheck, function ) # remove the callback om.MSceneMessage.removeCallback(cbk_id) You don't need to import the OpenMaya module a second time in your callback. Its already imported and the MScriptUtil is in a closure.
