Description of Problem:

The section 4.1.2.3 of the ICCCM implies that if a
window want to be
placed (by the wm) at the position it requests it
should set the
PPosition flags of the WM_NORMAL_HINTS.
(Note: I do not claim that the x,y field of the
WM_NORMAL_HINTS,
should be set to the requested position)

Steps to reproduce the problem:
1. Start the gnome-panel 
2. use xprop to see which hints are set
3. No PPosition ...

Actual Results:
With some wm a Top Panel is not placed correctly


Expected Results:
Top Panel always placed at the top

How often does this happen? 
Depends on the window manager

Additional Information:
Here a patch (current cvs, bugzilla probably break
my cut and past ...):
