Comment 21 for bug 284546

Same setup as above, I applied the patch from comment #17 into the stable inkscape-0.48.4.tar.gz (the same used with Homebrew, haven't managed to compile the latest from bzr yet.).
Here are the debug messages:
===

I am not familiar with the code, any suggestion what to do next?
