Description of problem:
sudo -u auser -s -H
dialog gives a segmentation fault
I'm guessing it can't access the terminal (permissions problem?)
the segmentation fault is presumably a dialog problem. a permission
denied message would be more friendly
the permissions might be an sudo problem?

Steps to Reproduce:
1.sudo -u auser -s -H
2.dialog --yesno test 20 10
Actual Results: Segmentation fault
Expected Results: a dialog box

seems to be s.th. like /dev/pts/[0-9]+ which /proc/self/fd/1 is
pointing to... so, you have to chown this before.
yes, this seems to be a problem of dialog..
