Eric,
It turns out that the key difference is in pygobject. I was using
2.13.2 (from source) here at work, and Ubuntu Feisty currently ships
2.12.3. 2.13.x is an unstable branch, of course, (gnome-related
packages follow the even/odd versioning scheme), so I shouldn't have
been using it to t

Yep. Nothing obvious. I'll have to have a look on Ubuntu and see if

When you get a chance, would you mind running the attached script? This
is how I was finding object leaks before. It takes a single commandline
argument that is the number of iterations. Can you send me the outputs
from 1 and 2 iterations? That way we should be able to see w

Not necessarily. By default, Python allocates large pools from the

All this sounds like great progress--thanks! I particularly appreciate
the descriptions of what problems you found and how you found them.

it is very important that Mike's patches be checked out and applied ASAP

More info on the memory leaks. It has to do with GtkToolbar.insert(). For

With it set to toolbar2, it is very noticably slower, and leaks 120k per.

Hi,
Thanks for this direction. I am using Numpy-1.1. Do I not supposed to use this
