The place that GEGL probably tries to swap is ~/.gegl/swap I'm not
sure what is going on here. Does this happen with the color reduction
filter as well? Please open a bug
so we can track this issue, perhaps even with an example XML file
provoking the issue (perhaps using fractal-explorer as source data or
some similar synthethic buffer as input.)
