Description of problem:

     In Gnome, the "Query" dialogue which comes up when running something from
the System Settings menu that needs root privleges like "Display" (or any of the
other 'redhat-config' utilities) has two buttons, one for "Okay" (if the
password has been entered), the other for "Cancel".  If the "Cancel" button is
clicked, an "Error" dialogue will pop up diplaying the text "Unknown exit code.".

Version-Release number of selected component (if applicable):

How reproducible:

     Click cancel when asked for the root password.

Steps to Reproduce:
1.  In Gnome, click on the Red Hat menu icon.
2.  Select the "System Settings" sub menu.
3.  Select "Display" or anything else that requires root access.
4.  Click the  "Cancel" button instead of entering the password.
    
Actual results:

     An Error box will pop up with an "Okay" button and the text "Unknown exit
code."

Expected results:

     Originally thought when clicking the "Cancel" button, the Query dialogue
would close with no other input.

Additional info:
     
     Not sure as to what else affects this, like if the Query dialogue is just
one dialogue for all utilities that require root or if each utility has it's own
Query dialogue.  I've tried it on redhat-config-xfree86, redhat-config-users,
redhat-config-samba, and redhat-config-date.
