I don't think it is that same icon. The agps-ui picture has a paler background. Compare the clock picture (I assume that this is qgn_indi_worldmap.png) to the one in /usr/share/agps-ui/worldmap.png and you'll see what I mean. I notice that the latter image is 696x396, which is presumably the size of the window under the default theme. Is there a clue there? The clock background is 1500x819!
