Description of Problem:


Steps to reproduce the problem:
1. Install Gimp 2.0.0 on Windows XP
2. Drag a guide from the ruler bar (either ruler).
3. Drag the guide back over the user bar or out of
the window.

Actual Results:

The guide remains intact and located exactly where
it was before you tried to get rid of it.

Expected Results:

I expected the guide to be disappeared, deleted,
gone, wiped out, stepped off this mortal coil, etc. :)

How often does this happen? 

All the time, every time.

Additional Information:

If you have the drawing window a little too large
or shifted so that you can see area outside of the
current picture, you can drag the guide to that
area and successfully get rid of it that way. 
However, this doesn't work very well if you use
lots of closely spaced guides and do most of your
work deeply zoomed in to the drawing (ahem).
