Undelete copies and deletes the file rather than moving

[Volodya]

Binary package hint: nautilus

Tried to post it as a confirmation to another bug but was told that it's a separate issue:

To reproduce:
Create a large file (the large one will allow you to see the difference between moving and copying+deleting)
Delete it
   Note that the file gets moved to trash almost instantaniously.
Now try to move it from the trash back to where it was.
   Note that the file first gets copied from trash, and only then deleted from there.

It causes other problems besides the speed, for example:
Create the file more than 1/2 of your free disk space.
Delete it.
Try to undelete it by restoring it to the same disk.
You will not have enough disk space (that's because there is no space for the second copy of the same file).

Thank you for taking the time to report this bug and helping to make Ubuntu better. Unfortunately we can't fix it, because your description didn't include enough information. You may find it helpful to read "How to report bugs effectively" http://www.chiark.greenend.org.uk/~sgtatham/bugs.html. We'd be grateful if you would then provide a more complete description of the problem.
 We have instructions on debugging some types of problems. http://wiki.ubuntu.com/DebuggingProcedures
At a minimum, we need:
1. the specific steps or actions you took that caused you to encounter the problem,
2. the behavior you expected, and
3. the behavior you actually encountered (in as much detail as possible).
Thanks!

1. The specific steps can be found in 'To reproduce' section of my original post (as well as 'example').
2. I expected undelete action to move the file from trash rather than copying it and then deleting it from trash upon the successful copy.
3. I have encountered copying the file and then deleting it from trash
