Description of problem:
Here's one that might bring major amounts of unintended pain.  As a
rule in the "Are you sure you want to do something possibly damaging?
yes/no" dialogs, if the user clicks the Close button on the dailog (X
in top upper-right window controls) the action should _not_ be taken.
 Currently it is.

Version-Release number of selected component (if applicable):
system-config-lvm-0.9.1-2.5

How reproducible:


Steps to Reproduce:
*** Please don't do this ***
1. Select your root partition in Uninitialized Entities
2. Click "Initialize Entity"
3. At the "Are you certain that you wish to initialize disk entity  
/dev/hda3? All data will be lost on this device/partition." panic and
click the close button.
  
Actual results:
Shot yourself in the foot.  You lost data you didn't want to lose.

Expected results:
Close should be interpreted as safely as possible, i.e. I don't want
to do this.
