I cannot reproduce *any* of the two behaviours when terminating gwenview
inbetween:

cd $(mktemp -d)
cp ~/photo1.jpg test.jpg
gwenview .
	# shows the thumbnail of photo1.jpg, and opens test.jpg with the
	# content of photo1.jpg
# quit gwenview
cp ~/photo2.jpg test.jpg
gwenview .
	# shows the thumbnail of photo2.jpg, and opens test.jpg with the
	# content of photo2.jpg


OTOH, when I keep gwenview running I see a different bevhaviour:
- thumbnail is properly updated
- actual photo is not update (still shows photo1.jpg!)

So it seems the thumbnail issue is fixed, but the display of the actual
photo not.

Thanks

Norbert
