>Description:
After the update of devel/ncurses to 5.8 rtorrent stopped working at least on FreeBSD/amd64. The problem are invalid canvas size parameter to ncurses. The attached patch can be put into net-p2p/rtorrent/files and fixes the problem by passing legal values to ncurses.
>How-To-Repeat:
Start net-p2p/rtorrent on a FreeBSD/amd64 box with devel/ncurses 5.8 installed.
>Fix:
See the attached patch.
