I ran into some trouble with rtorrent It builds fine inside scratchbox, but it generates a segmentation fault on the device when I add a torrent. I also tried the latest version from SVN. The same result. I'm afraid debugging will take some time...

It's ok to link to the deb file.

Also, I think it's normal behaviour for ctorrent to continue after finish downloading. I think it just continues as seed. (upload to other people)
