Comment 7 for bug 285558

Fix committed in the trunk, revision 9699.

The script now test if a layer is empty, and skip it if it's the case.

The file is available on launchpad (http://bazaar.launchpad.net/~inkscape.dev/inkscape/trunk/annotate/head%3A/share/extensions/gimp_xcf.py). To test the fix with 0.47 or 0.48, copy the downloaded file to the Inkscape share/extension folder.
