iconify all windows doesn't check the event type, and triggers "double-click" event as a separate button_press

What steps will reproduce the problem?
1. right click on the "iconify all windows" applet, click properties, check the 
"alternate iconify/shade..." box, press Close
2. make sure you have some windows open
3. double-click the button

What is the expected output? What do you see instead?
i expect it to trigger 2 utton clicks.
it triggers 3 clicks instead, because double-click is sent as a separate 
button_press event

What version of the product are you using? On what operating system?

Please provide any additional information below.
