Since it seems to be a fix, which indicates the issue is object ownership/lifetime, you can try an approach that avoids the warning.
For example, dont give item1 a parent, instead add it to the scene, and when deleting item0 add code to manually delete item1. You can also try using the API in http://www.riverbankcomputing.com/static/Docs/sip4/python_api.html to manually manage the object ownership, deletion semantics. Kovid.
