I have today managed to identify a repeatable trigger. Host=Windows 7 Professional 32-bit running on Dell Latitude E6510 (i7). Guest=Xubuntu 13.04 32-bit (upgraded from 12.10). Cairo-dock GLX. Closing Cairo-dock causes VirtualBox to crash! (Same result with xfwm4 compositor on or off.) Disabling 3D acceleration in VBox stops the issue. This did not occur with previous version of VBox.
