print a warning, and set the idletime variable for the entry to -1; then pick up the -1 later in sprint() and lprint() and ignore those idle times by printing just whitespace. When third party applications, such as kdm, insert utmp entries, they sometimes use strings like ":0", which can't be stat()'d and currently result in warnings that are not helpful to the user.
