Comment 2 for bug 145811

I am seeing exactly the same problem on both Feisty and Gutsy amd64. A python extension I am writing works on Edgy amd64. On Feisty and Gutsy, the code is being loaded, since a .pyc file is created and I can print to nautilus's stdout with a "print" statement at the toplevel. However, the methods in my derived class are never called to modify the contents of columns.
