I don't think you're missing anything. It's the OP that doesn't seem 
to be able to reply properly. Besides yours another answer appears at:

 Greetings;

 Fedora 8, gimp 2.4.6.

 I'm back again, trying to crop an image, again, yet, still.

 I can cut and cut and cut till I have what I want, but not even the zealous
 crop will get rid of the image area cut, it is still part of the image even
 if I draw it exactly enclosed,  cut it, and open a new blank image and
 paste, the white space at the top of the pix is still there.

 I've also saved the zealous crop results, and reloaded it, but the white
 space left after the cut is still, apparently forever a part of the image. 
 I don't want it, and I sure as heck don't need it restricting where
 guntenprint can put it on the paper because gutenprint will not allow the
 white space to be expanded off the edge of the paper.

 Darnit, I want to see the crosshatch indicating no data at all exists in
 that area once I have selected it and cut it away.  If I can do it in the
 darkroom on an enlarging easel  a pair of scissors (and I can and have
 many times in the last 60 years), why can't I do it in gimp?

 So what is the secret handshake that makes a cut operation a real, totally
 nuked, its ALL GONE cut as if the data went 100% into the bit bucket?

If I understood well your question,

Why don't you try to cut the image using the color selection tool and after 
saving the result image without saving the color of transparent pixels?

You can also delete the color of few pixels lefts after cutting manually.


Cheers,

Cuz you're not doing it right, apparently.  

To learn how to do this, try these steps (using GIMP 2.4 on Linux):
1. Choose the crop tool from the Toolbox - be sure it's the crop tool
and not a selection tool.  The crop tool is the one that looks like an
exacto knife.
2. Drag your outline around the area you want to keep in the canvas.
The outline is a solid line with drag boxes at each corner and along
each edge (you can ignore the drag boxes for this tutorial).  The
selected area should look normal.  The unselected area is darkened.
3. Hit the ENTER key to apply the crop.  The mouse (of course) musts be
in the canvas for the ENTER key to apply to the crop operation.

As an added step to verify the cut:
4. In the Layers dialog drag the layer into the Toolbox.

You end up with a new image that is the cropped area of the original.
Note that the original is also cropped.  

You're problems are probably that you're not using the crop tool
correctly or not using the crop tool at all (using a selection or
similar instead and cutting out the stuff you don't want in a layer that
does not have an alpha channel).

I'm not understanding you any more than the other two people
who have already replied, but I have a couple of guesses:

First, the magic word for crosshatch indicating no data at all
exists is transparent or alpha (never mind why alpha means
transparent; remembering it will make a lot of other things
easier). If you're cutting things out of an image and getting
white (or some other color) when you wanted to see the grey
checkerboard pattern, that means your image doesn't have an
alpha channel (in other words, it doesn't allow transparency).
Add one with Layer-Transparency-Add Alpha Channel. If that's
greyed out, then you already have an alpha channel and that's
not the problem.

Second, though you're saying crop I get the impression you might
actually be trying to select stuff and clear it (make it
transparent). Crop is when you start with a big image (e.g.
800x600), and you want to take only some rectangular portion of it,
to make a smaller but still rectangular image.

If you're trying to end up with a shape that's not rectangular --
e.g. cut away all the white area around some central object to
make everything transparent except the object -- then crop is not
what you want. In that case, what you want is to select the part
you want to cut away and do Edit-Clear (which will make it
transparent *if* your image already has an alpha channel, otherwise
it will just make it whatever background color you have set).
Alternately, select just the object you want, and do Edit-Copy
so you can paste it somewhere else.

If none of us has guessed right about what you're trying to do
and you're still frustrated, try telling us what sort of image
you're starting with and explaining the steps you *are*
following, what happens and what you expected to happen.
That might clear things up.

You might even attach the image in a reply to me ( patrick at 
dbp-consulting dot com) and tell me what you want to happen.  I'll do 
that to the image, and then tell you step by step what I did to 
accomplish it;)
