This problem doesn't relate to the older bug, but the mention of gnome-vfs in both that bug and the error message inkscape prints helped me track down the bug. As a workaround for http://bugs.debian.org/626076 , which causes Firefox to crash, I had commented out the line "file: file" in /etc/gnome-vfs-2.0/modules/default-modules.conf . Uncommenting that line fixes this problem, though it disables the workaround for the other gnome-vfs bug.
