I found a temporaly and dirty fix. Rename de config folder for transmission and when it start then it generate a new folder "clean"
$ mv ~/.config/transmission ~/.config/transmission_backup $ transmission Then start transmission. Other fix: The file ~/.config/transmission/settings.json seems be corrupted and its empty! You can open these file and put the initial values (from the new folder generated for transmission): My settings.json (you should be some values) { "blocklist-date": 1232747180, "blocklist-enabled": 1, "blocklist-updates-enabled": 1, "debug-message-level": 2, "download-dir": "\/home\/shakaran\/Escritorio", "download-limit": 100, "download-limit-enabled": 0, "encryption": 1, "inhibit-desktop-hibernation": 0, "lazy-bitfield-enabled": 1, "main-window-height": 500, "main-window-width": 474, "main-window-x": 756, "main-window-y": 78, "max-peers-global": 200, "max-peers-per-torrent": 50, "minimal-view": 0, "open-dialog-dir": "\/home\/shakaran", "peer-port": 51413, "peer-socket-tos": 8, "pex-enabled": 1, "port-forwarding-enabled": 1, "prompt-before-exit": 1, "proxy-authentication": "", "proxy-authentication-required": 0, "proxy-port": 80, "proxy-server": "", "proxy-server-enabled": 0, "proxy-type": 0, "proxy-username": "", "rpc-authentication-required": 0, "rpc-enabled": 0, "rpc-password": "SyUiMtANj6IBeYED", "rpc-port": 9091, "rpc-username": "transmission", "rpc-whitelist": "127.0.0.1", "rpc-whitelist-enabled": 0, "sched-begin": 1380, "sched-download-limit": 200, "sched-end": 420, "sched-limit-enabled": 0, "sched-upload-limit": 100, "show-filterbar": 1, "show-notification-area-icon": 0, "show-options-window": 1, "show-statusbar": 1, "show-toolbar": 1, "sort-mode": "sort-by-name", "sort-reversed": 0, "start-added-torrents": 1, "statusbar-stats": "total-ratio", "trash-original-torrent-files": 0, "upload-limit": 50, "upload-limit-enabled": 0, "watch-dir": "\/home\/shakaran\/Escritorio", "watch-dir-enabled": 0 } The major problem is only a settings file that it is empty!
