Bug description:
Binary package hint: f-spot

TIFFs generated as multilayer composites with Hugin are not displayed properly in f-spot; only the top layer is displayed, cropped to its dimensions.

To reproduce: Load the attached file with "f-spot -v small-test.tif".

f-spot only displays the top layer, cropped to its dimensions--the image should be around 500 pixels wide, but it displays as only the width of a single layer. I do not know if multipage TIFFs are stored as multiple layers; if they are, it would be inappropriate to display them as one big image. However, if the layers are all painted on the same canvas, as these are, they should be displayed as one large image.

The layers are visible when checked with ImageMagick, and they display properly-overlapped in Gimp.
