As I see, this is not a bug of nautilus-sendto, but thunderbird (don't exactly know is it bug or feature). Thuderbird doesn't understand percent-encoded file uris. So here is my perl-written nautilus-script which does it well (works with many, non-ascii encoded, full of spaces files). And the next step is implementing filter (which could be found in script) right in /usr/bin/thunderbird. Toggle in attachment.
