"I am using f-spot 0.4.3.1 on ubuntu 8.04. I have a bunch of tif images from a photo cd that I am trying to import. The jpg versions import just fine, but the tif versions give me the import error, "object reference not set to an instance of an object." If I select "skip" the program continues happily importing more jpgs, but it will give me that error for every one of the tif files.

Document viewer also has trouble with these files, but gthumb can open them just fine. I opened one of them in Gimp and re-saved as another tif file and that can be imported just fine, so it's something about the specific encoding that's not being supported, I think. I will attach both files."
