Can you reproduce the bug or give some details what you did before it crashed?
Comment 2 wintonian 2013-02-02 21:46:10 UTC 
Well it hasn't happened again.

I created the image by using the scanner which I then saved as a JPEG and opened up in Krita, where I clicked on the icon for the rectangular selection tool, I selected the desired area and Krita crashed.

I know that probably doesn't help much more but it's all I did so can't add anything else. Sorry.
