Comment 17 for bug 160738

This definitely has nothing to do with the gnome-common package. I think it is a general gtk+ issue though, so am moving to the gtk+ package. It seems like gtk+ should be positioning near the focus instead of the mouse, which it is doing now. All the key does is cause a right-click event to be simulated, and is not treated specially different from a right click, which is presumably why the behavior is the current way.
