Please describe the problem:
Hello,

While importing a directory I have the error "Object reference not set to an instance of an object".
Having a look at my .xsession-erros file it seems the error is raised at "parsing ImageWidth" (see the stack below).

Steps to reproduce:
1. Import the image located at http://cdadhemar.free.fr/f-spot/31_2006_-000003.JPG


Actual results:
I have a popup window with the message "Object reference not set to an instance of an object".

Expected results:
I would expect the image to be imported correctly

Does this happen every time?
yes

Other information:
Please notice that I used Digikam before f-spot. The image may contains digikam infos not recognized by f-spot (exif data, tags, descriptions ...).

Here is the stack for info :
