Default Nexus 7 photo editor crashes

Hi all.
I have a 2012 model which is running the latest Android update (4.4.2).
I've noticed that whenever I import a photo from my Canon S95 camera and try to edit using the native photo editing s/w, upon saving the gallery crashes and the original photo is lost. I've tried to show this in the attached screen shots.

Has anyone else seen this behavior? I think it's a Kitkat problem as I've tested on my parent's Nexus 10 with the same results.
It does seem to be only files that are imported from the camera that are affected, others have edited and saved ok.

Thanks for any help..
