Description of problem:
There appears to be a severe X resource leak in the Gimp. When 
creating an HSV graph, the X memory footprint goes from around 90M 
virtual to over 400M in about 30 seconds.

On the 256MB machine where I first noticed this, the machine started 
page thrashing so badly it needed to be hard reset (probably worth a 
kernel bug report there). On a bigger memory machine that can 
survive, the X server does not appear to release the memory even 
after the Gimp exits - but I'm still assuming that the root of the 
problem is a resource leak in the Gimp.

Version-Release number of selected component (if applicable):
gimp-2.2.3-0.fc3.2

How reproducible:
Always

Steps to Reproduce:
1. Open Gimp.
2. Create new image. I used 640x480 RGB.
3. Go to Script-Fu -> Util -> Draw HSV Graph... and OK with default 
parameters.


Actual Results:  The Gimp chugs along and the X server's memory 
baloons wildly.

Expected Results:  Drawing the HSV graph should not cause X server 
resources to baloon out of control.

Additional info:

Machine is up-to-date FC3, with:

kernel-2.6.10-1.760_FC3
xorg-x11-6.8.1-12.FC3.21

The machine is using the X.org "nv" driver for a GeForce4 Ti4200 card 
(128MB).

I marked the severity high because the leak is so severe - on a lower 
memory machine, it can push the machine into uncontrollable page 
thrashing and effectively freeze the machine solid after 30-45 
seconds.
