Description of problem:
I'm using vnc to connect to a CentOS 5.1 system. So basically RedHat Enterprise 
Linux 5.
When I do that, the display variable is set to "localhost.localdomain:1.0".
If it is like that, I cannot open the Service Configuration Tool.
My workaround is that I reset the display variable to ":1.0" in the
.bash_profile:
DISPLAY=`echo $DISPLAY | grep -o :.*`
export DISPLAY


Version-Release number of selected component (if applicable):
0.9.4-1.el5.noarch

How reproducible:
Set DISPLAY variable to "localhost.localdomain:0.0" and run command in shell


Steps to Reproduce:
1. DISPLAY=localhost.localdomain:0.0
2. export DISPLAY
3. system-config-services
  
Actual results:
Window doesn't appear

Expected results:
Window appears
