I too am getting the same issue. However, for me the crash doesn't happen until I try to resize the window - like exiting from full screen via F11 or even just exiting the application. In addition, just attempting to switch to a different workspace also causes X/Unity to hang!
On my system, CTRL+ALT+Backspace has never worked. However, I can CTRL+ALT+F1 and from there restart lightdm and all is well again! I'm running Ubuntu 15.10: $ lsb_release -a No LSB modules are available.
