Stopping


Steps to reproduce:
1. open f-spot
2. import large collection of photos, disselect "copy to directory"
3. click import


Actual results:
you can see the f-spot process crawling the directories to import, and when import starts, an error message comes up saying  "A null value was found where an object instance was required."


Expected results:
that it would import the photos and put them into the database

Does this happen every time?
yes!
