 Well, yes and no. The problem looks to be that the utmp file has
 "/dev/pts/51" in it (in the ut_line field) instead of just "pts/51",
 which is what would normally be expected.
 
 What do you see as the tty names when you run /usr/bin/who? And what
 program are you using to "log in" on these ttys that leaves it set
 this way? (sshd? xterm? kterm? gnome_terminal? ...?)
