Automatic Crop - if no image is opened then crash appears

[grofaty]

The latest development version of Pinta on Ubuntu 11.10:
1. Close all images in Pinta.
2. Use Image | Automatic Crop.
Pinta crashes with error:
==========

Doh! Should have thought of that. Will fix along with the keyboard shortcut and naming.
