For the record, I was asking because oxygen (from "master") as well as 
oxygen-transparent do access some QPixmap::handles to pass them to kwin 
for the new shadow system.

The access should be safe though, since if the handle returned is 
invalid, then a native X11 pixmap is created directly, instead of 
re-using existing QPixmap.

I do get the warning here, using kde from master, and Qt 4.7.2, 8 times 
per app, for all applications when using raster graphics system. It 
usually happens the first time a menu is opened, which corresponds to 
the X11 pixmaps creation in oxygen.
