Description of Problem:
Drag and drop from large archives tempramental.
Drag and drop from file roller dropping back into file roller window causes
unexpected behaviour.

Steps to reproduce the problem:

1. Open a large tar.gz archive (I'm using a 4.8Mb one here)
2. Drag archive contents from file roller window to nautilus window
3. Archive appears to be been unpacked while dragging in progress.
4. Letting go of mouse button on window before archive has extracted
doesn't copy the archive contents to the folder.
5. Dropping the dragged item to be extracted back into file roller causes
file roller to try and add the files to be extracted back in to the archive
(at least, that is what it look like it is doing). This occassionally
results in archive corruption, causing file roller to bailout with:

An error occurred while loading the archive.
tar: Unexpected EOF in archive
tar: Error is not recoverable: exiting now


Expected Results:
Archive is expanded after folder is dragged to nautilus window, so drag and
drop remains responsive.
Dragging the cursor back into the file roller window during drag and drop
should not make file roller try and add the files back into the archive.

How often does this happen? 
Every time - delay between start of drag completion of archive extraction
depends on size of archive.

Additional information:

Maybe this is two seperate issues?
