Thanks for reporting this bug. I can confirm that the file will not open (using the same Ubuntu & Inkscape versions as you) and that replacing the non-ascii character allows the file to be opened.
How did you edit the metadata? Did you directly enter it using the XML editor in Inkscape or did you use File->Document Metadata?
