Bug description:
If you drag a group of files from the desktop into a folder on Docky, causes very strange behaviour.

For example, if you have 4 files, A, B, C and D, select them all, drag them over a folder and when it says "release to open" drop them to place them in the folder. File D gets moved to the folder but renamed A. libnotify  (the notification app in Ubuntu) says "moving D... 00.0% Complete" and never disappears. No how long you leave it, nothing changes.

This bug could lead to loss of data as if you try to move the file back, it now has the same name as one of the other files!

The folder doesn't matter which one it is but for the purposes of this example, it was the pictures folder (~/Pictures) which was empty before
