Apart from the missing icon, Opera 10.11 is working here on three computers. I wouldn't have noticed the icon problem had it not been pointed out because I don't use the "start" menu much. I use a launchbar I create in the XFce Panel where I have something like what's called drawers. I select icons myself.
If one disappears I know the icon is either gone or not in the location I specified. So I either find it or change it.
If the only fix in the forthcoming new package is the icon thing, I'll pass because I already fixed it myself.
