The Gimp UI after cropping. The frame is shifted.

When I select a rectangular portion of an image and click Image -> Crop to Selection, the selection doesn't cover the resulting image. Instead, it is shifted to the right and down by the original offset.

Example:

1. Create a new 400x400 pixel image.
2. Select a rectangle at 100,100 (upper left corner) with size 200x200.
3. Click Image -> Crop to Selection

The image is now cropped: OK
The moving ant line surrounds the image: OK

But the frame which can be dragged to resize the selection is still at 100,100, when it should be at 0,0.
