Bug Description
When I run GEGL's C2G operator:
- The operation hangs (it does not crash, it just hangs) more or less in the middle of the process.
- The operator works in rectangles. Some of these rectangles are obviously darker than the rest of the image.
- I takes way longer than before. Maybe the parameters have changed their meaning or the internals have changed, and the iterations and samples have to be lower. I don't know right now.
I usually run at a radius of 1600, 40 samples, 20 iterations on 16MPix images (4928 x 3264).

I've done further testing.
With smaller images, thus lower radius and iterations/samples, the problem still arises.
I've done some tests with the "gegl" command line command, and it works just fine. I can definitely apply the operator with something like:
gegl -p -o /home/esteve/1.png -x "<gegl><node operation= 'gegl:c2g' ><params> <param name='radius' >1800</ param>< param name='samples' >16</param> <param name='iteration s'>16</ param>< /params> </node> <node operation= 'gegl:load' ><params> <param name='path' >/home/ esteve/ 2.png</ param>< /params> </node> </gegl> "
It applies the operation and saves the result, so I'd say the problem resides in the GIMP, not in GEGL, or at least in the link between the two.
