Nautilus probleem: Cannot open js_0012-Illusions.jpg

[Kees de Bruin]

Met de laatste Ubuntu Dapper krijg ik de volgende melding voor een 
willekeurig JPG bestand:

 >>>
The filename "js_0012-Illusions.jpg" indicates that this file is of type 
"jpg document". The contents of the file indicate that the file is of type 
"JPEG image". If you open this file, the file might present a security risk 
to your system.

Do not open the file unless you created the file yourself, or received the 
file from a trusted source. To open the file, rename the file to the 
correct extension for "JPEG image", then open the file normally. 
Alternatively, use the Open With menu to choose a specific application for 
the file.
<<<

Ik kan de file wel via "Open With" bekijken, maar het programma wordt niet 
onthouden. Hoe kan ik de boel zo configureren dat hij de instelling blijft 
houden.
