[Bug 1029371] Re: drag&drop of files randomly silently fails

 

Yes, I have just tested on 15.04 and I still observe the issue, or at
least this part:

As in the original report, it happens randomly, and maybe not as often
as I seem to remember it used to.


One note that may (perhaps) help in triaging the issue:
- I now have the Launcher always visible on the left (as opposed to auto-hide/show)
- When I observe the issue (i.e. I drag and drop a file on the desktop and it does not move to the destination position), I observe that the Launcher sort of "flashes" at the very moment I drop the file and it isn't moved (more precisely, icons that are not possible destinations for the dragged file in the Launcher get greyed out for a fraction of a second)
- When I do *not* observe the issue, EITHER I've done it so quickly that the Launcher didn't have time to change its status, OR it did completely, and application icons that are not candidates for accepting the drop have been greyed out for a while.


In my few tests I've just done, I have observed this coincidence all the times; however it may have been random.

Title:
  drag&drop of files  randomly silently fails

Status in Unity:
  Confirmed
Status in unity package in Ubuntu:
  Confirmed

Bug description:
  I'm not sure whether this is Nautilus or Unity at fault. This happens
  with both a Nautilus window and the Desktop:

  1. In a Nautilus window: click on a file icon, drag it and drop it
  over a folder. Or hold the Ctrl key and click and drag and drop the
  file immediately in almost the same place where it was.

  In the first case (dragging over a folder) the file should be moved;
  in the second case the file should be copied. In both cases, if you do
  it quickly enough, the action is completely ignored and nothing
  happens.

  It seems to be related to the fact that the Launcher (or whatever it
  is called) shows up on the left of the screen when you start dragging.
  If its show-up animation is not complete when you drop the item, the
  drag&drop operation is ignored.

  2. On the desktop, the same happens. Or if you simply move an icon (in
  which case the expected behavior would be for the icon to snap to the
  nearest position in the grid and stay there) you can also observe that
  the action is ignored and the icon goes back to its original position.
