scope-runner-dbus.py crashed with SIGSEGV in ffi_call_unix64()

[iMac]

Occurred when I was uninstalling an Extension pack 4.2.16 from VirtualBox 4.2.18 running on saucy, using the GUI.

I had just purged Saucy 4.2.16 Ubuntu package and upgraded to 4.2.18 from virtualbox.org apt repositories for raring.

The 4.2.18 packages from official virtualbox repositories were built for raring (but meet saucy dependencies) and I had unity-scope-virtualbox package installed. I expect something the saucy scope package couln't handle related to the newer virtualbox package.
