Upgraded to the latest rtorrent / libtorrent today: Code:libtorrent-0.12.4 BitTorrent Library written in C++ rtorrent-0.8.4 BitTorrent Client written in C++ rtorrent came with a revised rtorrent.rc, but unfortunately the syntax for sending data to rtgui bombs rtorrent: .rtorrent.rc: Code:scgi_port = localhost:5000 result: Code:rtorrent: std::bad_alloc rtorrent was rebuilt from scratch with xmlrpc support enabled. Another problem appears to be 'stop_on_ratio'. The syntax has changed slightly (some double quotes were added to the syntax), but the error persists. .rtorrent.rc Code:schedule = ratio,60,60,"stop_on_ratio=110" (variants without double quotes, or using the default three values, no difference) result: Code:Scheduled command failed: ratio: Command "stop_on_ratio" does not exist. Just checking to see if other people have this problem before making a PR.
