A DESCRIPTION OF THE PROBLEM :
Start the sample Java application provided in "Steps to Reproduce", press the button, a dialog is displayed, press the Shade button on the dialog title bar (the Shade button exists on the title bar of KDE windows), press the Close button on the same title bar. The dialog should be closed but it remains on screen. Now press the Unshade button. The dialog is a grey rectangle. If I repeat the previous actions I get another grey rectangle, etc. All the rectangles are removed from screen only when I shut down the application.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Start the sample Java application provided in "Steps to Reproduce", press the button, a dialog is displayed, press the Shade button on the dialog title bar (the Shade button exists on the title bar of KDE windows), press the Close button on the same title bar. The dialog should be closed but it remains on screen. Now press the Unshade button. The dialog is a grey rectangle. If I repeat the previous actions I get another grey rectangle, etc. All the rectangles are removed from screen only when I shut down the application.


EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The dialog should be closed when I press the Close button of the dialog.
ACTUAL -
The dialog is not closed when I press the Close button. If I repeat the steps I get another dialog which is not closed.

REPRODUCIBILITY :
This bug can be reproduced always.
