unity-2d-shell crashed with SIGSEGV

[Stéphane Guillou]

Not sure how to reproduce this. It happened when I was opening two Calc spreadsheets and tried to switch back to Firefox and Nautilus by clicking on the launcher.

I'm on a Samsung N310 netbook.

I have installed the ubuntu in my computer few days back but i had left the update manager on , due to which it may have installed a newer version of unity 2D shell or any dependency of it that causes unity 2D shell to close unexpectedly.
