Description of problem:
The Ctrl-Z keyboard shortcut to undo a crop doesn't seem to work.

Open an image.  Select the crop tool.  Pick out a section of the 
image (in my case, a B&W GIF of some text, I selected one word).  
Click the 'crop' button on the dialogue box.  Fine so far.

Now save the (small) image and press Ctrl-Z to undo the crop in order 
to pick out another part (in my case, another word of the text).  
Ctrl-Z seems to have no effect, although Edit->Undo does work.

Version-Release number of selected component (if applicable):

How reproducible:
