Bug Description

There's a corner case where if nautilus hasn't been started, or if the nautilus window is unmapped for whatever reason, then compiz will be unable to find a window to stack the next newly created window /above/ when it is mapped. When this happens, PrivateWindow::findSiblingBelow returns NULL and CompWindow::updateAttributes silently fails and leaves the newly created window at the top of the stack.

In this case, it only makes sense to place the window at the bottom of the stack.

Steps to reproduce:

 1) Start a clean session
 2) Kill nautilus enough times that it isn't there on the desktop, or relocate the nautilus binary
 3) Start unity
 4) Open any application - it will be above the panels and launcher
