Brought to you by:

some rTorrent versions produce garbage where some path elements are empty strings. this leads ctorrent to do things like:
$ ctorrent -c foo.torrent
error, unsafe path "/foo.bin" in torrent data for file 1
Torrent metainfo file data is invalid or unusable.
error, initial meta info failed.
simple attached patch works around this issue.
