Please describe the problem:
I often extract files by dragging them out of the file-roller window onto the Desktop or into a Nautilus window. When a drag-drop starts however, file-roller starts some processing that I presume is copying to a temporary directory. If you complete the drag-drop before this copying is complete, the files are extracted partially. This is a greater problem when you extract an extensive or large directory structure, since you must wait with mouse button depressed for the processing to complete.

Steps to reproduce:
1. Locate a large zip file with extensive directory structure.
2. Drag drop directory onto the desktop quickly


Actual results:
The directory is extracted partially

Expected results:
Everything extracted correctly

Does this happen every time?
Yes
