 After skimming through it once more, can you confirm that it originates from 
the window updating its _NET_STARTUP_ID property? I think it is possible that 
KDE apps update this property (to the same value) upon every window map. 
However, while not needed and not exactly nice, if this is the cause, the 
problem is technically still in Metacity - the startup ID by the time of the 
desktop switch should be already obsolete (startup sequence ended), so 
Metacity should not react to it at all.
