Shotwell crashes / greys out on launch

[Oscar Tiderman]

First time I started Shotwell it launched fine and I imported all of my pics (local only). Now when I try to start it the window becomes unresponsive (greyed out) before I get to see my pics, it won't even launch properly. I imported about 2000 pics to it the first time so it's no massive library causing this.
