unity-window-decorator crashed with SIGSEGV in gdk_window_get_events()

[Elthommo]

Binary package hint: compiz

The window borders disappeared whilst doing an updated. Also, I tried the propriety Ati graphics driver previously and it could not draw the whole screen at once so the driver was removed. This happened after restarting without the ATI driver.
