When trying to the the file nixnote-1.4_i386.tar.gz, gzip states there is an unexpected EOF.
$ gzip -d nixnote-14_i386.tar.gz
gzip: nixnote-1.4_i386.tar.gz: unexpected end of file
I notice that the file size is 7.7 MB while the x64 tarball is 77.9MB. Perhaps there was an upload problem? I have downloaded from several mirrors and have had the same problem.
$ md5sum nixnote-1.4_i386.tar.gz
