Hi, I am just creating a simple footprint and Kicad breaks (using the last nightly build on Ubuntu).
Does someone have the same problem?

Steps to Reproduce it:

    Launch Footprint Library Editor (from Kicad main window)
    File > Set Active Library > “My current library”
    New Footprint (from the icon on the toolbar)
    Enter Footprint Name (on the New Footprint popup)
    ENTER or Ok
    Kicad suddenly closes

Actually, steps 1, 3, 4 and 5 are enough to make it break.
