Comment 9 for bug 499257

I had the same problem with Inkscape 0.47 and Ubuntu 10.04.

- downloaded UbuntuLogo.svg from https://wiki.ubuntu.com/Artwork/Official
- installed Ubuntu logo by running "sudo apt-get install ttf-ubuntu-title"
- opened UbuntuLogo.svg with Inkscape 0.47
- removed the Ubuntu name and changed it to something else using the ubuntu title font
- saved to another svg file
- closed Inkscape
- tried to open the saved svg file and got the error message "failed to load the requested file"

I solved it by removing all <?xpacket [...] ?> tags.
