Please describe the problem:
Seen using gnome 2.18.3 and gnome-terminal 2.18.1.

Using two screens with DISPLAY of :0.0 and :0.1, a gnome terminal started on one of these sometimes has a DISPLAY of the other.

The problem does not affect the terminal itself, but all programs started in the terminal (if they use X).

Steps to reproduce:
1. On :0.0 start a gnome-terminal, 
   in the terminal type 'echo $DISPLAY', 
   you should get :0.0
2. On :0.1 start a gnome-terminal, 
   in the terminal type 'echo $DISPLAY', 
   you should get :0.1
3. Repeat 1 and 2, 
   after a few repetitions the DISPLAY echoed is the same
   on both displays.
   
   Closing down the gnome-terminals may make the problem disapear,
   until you again starts a number of terminals (alternating between the
   displays).



Actual results:
see above

Expected results:
The DISPLAY environment in the gnome-terminal should be the same as the place where it's started.

Does this happen every time?
After sufficient repetitions, yes

Other information:
This problem may be related to another problem reported as bug 463361 - where the gnome terminal sometimes changes the DISPLAY.

I am only running one X server (one Xorg process).
