Description of problem:

I sudo su -l to root (don't know if that matters) in a gnome-terminal.
I run the command nslookup mirrors.fedoraproject.org which gives
me a screen that contains:

[root@zooty ~]# nslookup mirrors.fedoraproject.org
Server:		68.87.74.162
Address:	68.87.74.162#53

Non-authoritative answer:
mirrors.fedoraproject.org	canonical name = wildcard.fedoraproject.org.
Name:	wildcard.fedoraproject.org
Address: 209.132.176.120

(and that wasn't easy to get into this form :-).

I put the mouse at the open bracket of the prompt and move diagonally
downward in an attempt to select the entire command and output (basically
what I have above).

Before I get very far into the selection process, the gnome-terminal
simply disappears.

Version-Release number of selected component (if applicable):
gnome-terminal-2.23.6-1.fc10.x86_64

How reproducible:
