Comment 2 for bug 132456

Agreed; this bug is a special case of bug 87023, but only because something is wrong in kdesu/sudo that is causing it to be unable to figure out which tty a command is being run from. This is seen in the sudo cache, as tty "unknown":

 # ls -l /var/run/sudo/kees
 total 0
 -rw------- 1 root root 0 2007-08-16 16:23 unknown

This should normally match the output of "tty". (e.g. "2", etc)
