Fernando,

Here is some more information about profiling that others may find useful:

1) The profile module reports times that are much longer than normal; I 
don't know to what extent the relative times are still correct; my 
impression is that they do still give a decent idea of where the 
bottlenecks and resource hogs are.

2) The combination of hotshot and hotshot2calltree (or similar) gets 
badly confused by duplicate function names such as __init__, so the 
kcachegrind view can be quite misleading.

3) A solution is to use the cProfile module in Python 2.5 with an 
appropriate reformatter.  The following script runs a python script 
through cProfile and generates a *.log file that kcachegrind reads:

http://www.gnome.org/~johan/lsprofcalltree.py

So the sequence is simply

python lsprofcalltree.py testscript.py
kcachegrind testscript.py.log &

Here are a couple of relevant Google results:

I suspect you're running an earlier version of pygtk than I am that 
doesn't have pygobject_version.

Please update matplotlib and try again.

Thanks for finding this bug.

Cheers,
Mike
