ICE default IO error handler doing an exit(), pid = 11281, errno = 4
I do not think there is a problem deleting the .ICEauthority file. That folder holds torrent cookies probably from a private tracker or something. I still believe ktorrent is one of the best torrent clients because it gives a timeout time to stagnate torrents and tries to load up active ones. In other words, the client always tries to make sure it is working with active torrent sources.
