Zoom indicators indicate completely wrong magnification

Binary package hint: digikam

In all the major display windows I get changing and mostly incorrect zoom factor indicators. As an example, as I look at the main screen of digikam right now, I have an image loaded with 4077x5000 Pixels, the image is displayed in its entirety plus the frame from digikam itself on a 1920x1080 monitor, yet the zoom indicator (that slider in the right bottom of the frame which lets me change how large the image is shown) tells me I'm at 87%. Given that only about 1500 pixels (in horizontal direction) of monitor real estate are occupied by the image as displayed on the monitor, the zoom factor should be below 30%.
