Doesn't extract full selection when clipping from an existing sound file.

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Bring up the menu on an existing sound file
2. Choose the "Edit" option
3. Zoom in so about 5-10 seconds are on the screen, select a short segment (~5 
seconds)
4. Preview the ringtone.

What is the expected output? What do you see instead?
The expected output is a clip composed of the highlighted area.  Instead, I get 
the clip from the beginning of the highlighted area to somewhere before the 
"selected" end.  It appears to stop where the left side of the end "handle" 
extends out, so the sound gets cropped a half-second or so too early.  
Visually, where [===] is the handle and | are the selection start/end:

|           |
|           |
|           |
