Comment 46 for bug 418242

same here.
"Inkscape has received additional data from the script executed. The script did not return an error, but this may indicate the results will not be as expected.

You need to install the UniConvertor software.
For GNU/Linux: install the package python-uniconvertor.
For Windows: download it from
http://sk1project.org/modules.php?name=Products&product=uniconvertor
and install into your Inkscape's Python location"

if they mean media-gfx/uniconvertor - it is yellow masked.

Also immediately afterwards, I get this error:
"No matching node for expression: /svg:svg/@sodipodi:docname
Traceback (most recent call last):
  File "gimp_xcf.py", line 185, in <module>
    e.affect()
  File "/usr/share/inkscape/extensions/inkex.py", line 215, in affect
    self.effect()
  File "gimp_xcf.py", line 43, in effect
    docname = self.xpathSingle('/svg:svg/@sodipodi:docname')[:-4]
TypeError: 'NoneType' object is not subscriptable"

and new popups come up every few seconds - with skill and a lot patience, I was able to safe my work...

inkscape used to work pretty stable for me - what happend? is this a python problem? (i updated python to 2.7 not so long ago, but i ran python-updater). does inkscape depend on uniconvertor? than why does it not come in as dependency? also, m revdep-rebuild claims everything is consistent.

media-gfx/inkscape-0.48.0 was built with the following:
USE="gs lcms (multilib) nls spell -debug -dia -gnome -inkjar -wmf"
CFLAGS="-march=native -O2 -pipe -fomit-frame-pointer -msse -msse2 -msse3 -mmmx -fno-strict-aliasing"
CXXFLAGS="-march=native -O2 -pipe -fomit-frame-pointer -msse -msse2 -msse3 -mmmx -fno-strict-aliasing"
