This is indeed a bug in knights, see my comment from 2006-11-07 15:57 at http://sourceforge.net/tracker/index.php?func=detail&aid=1587926&group_id=31461&atid=402242
The patch is attached to the sourceforge's bug report, to be sure I attached it here as well. Could the package maintainer fix this please in ubuntu so that we don't have to wait for the next knights release? ** Attachment added: "Fix castle crash in knights" http://librarian.launchpad.net/4975903/patch.castle_crash -- crashes when trying to perform castle (king/rook exchange) https://launchpad.net/bugs/70424 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
