installer crashed while trying to install system

[Matt McDermott]

I was trying to install Lubuntu 12.04 from a live usb and the installer keeps crashing while trying to install the system on my laptop. It has done this twice, the bar at the bottom said it was "Installing Packages" when it crashed both times.
