The error mostly occurs when importing non-georeferenced images into a
lat/lon location.

Non-georeferenced images are normally imported with the lower-left
corner at (0,0) and with a resolution of one unit per cell. For a
lat/lon location, this typically results in the top edge of the image
being above 90 degrees, hence the error.

You may be able to get around this problem by changing the location to
x/y while importing the image, and changing it back after the image's
bounds have been set correctly.

It can sometimes occur when importing geo-referenced images where the
top row is centred on 90N, resulting in the top edge being half a cell
above that. I am not aware of any workaround for this case.
