I encountered a similar bug working from the notes view in Impress.  When I
clicked on a different slide Impress would occasionally jump to the first
slide, and in the process another slide would be copied or moved.  This was a
very sporadic bug, and hard to reproduce, but I managed to replicate the
duplication behavior with the following procedure:

Initial state: Create a presentation with 20 slides that includes both an
auto-slide number in the footer, as well as a self verifying text label of the
initial slide number so duplication or movement of slides can be easily
detected.  Start from the first slide in this presentation:
1. Hover the mouse over one of the slides in the slide panel on the left and 
   mark the location of the duplicate icon with tape or sticky note.
2. Click on the notes tab, and then switch to another slide that is far enough 
   down the list in the slide panel on the left that slide 1 is no longer 
   visible. Make sure that another slide is present where the mark from step 1 
   is located.
3. Click into the notes text box as if you were going to enter some text, and 
   make sure the cursor changes to a text entry cursor.
4. Next click on the spot marked in step 1.

Bug Behavior: The slide view and slide panel will jump to the first slide. 
Occasionally either the slide that was initially selected before the jump, or
the slide the cursor ends on after the jump will be moved or copied in the
list.  This is a very sporadic behavior, and it may take 10 or more attempts to
replicate the duplication bug, but it is more likely to occur if the initial
click or end position after the jump is on the duplicate icon.

This behavior seems to be a side effect of the loss of focus bug (125911,
125013, 125707, 125708), and a result of selecting another slide when a jump
occurs.  I have seen both moves and copies of either the slide at the initial
cursor location or after the jump, but both moves and copies are very rare. 
The critical diagnostic feature is the presence of the jump back to slide 1 in
the slide panel.

Although this replication took place in the notes view, this same behavior can
be replicated in the normal view, but it is much harder to reproduce as the
loss of focus bug is much less likely in normal view.  Working with PowerPoint
files, or files that have extensive changes (>20) since the last save seem to
exacerbate the issue, and make the jump, and the concomitant move or copy much
more likely.  As such, immediately saving the imported PowerPoint file to the
native .odf format and then reloading, and saving work regularly might both
help mitigate this issue.

If the jump to the first slide is not a symptom of the behavior, there are a
few follow-up tests that might highlight other causes of this behavior:

1. Try working with the same files on a different computer system.  While I 
   have replicated a similar issue with a file created in AOO, there may be 
   other issues with importing files or the custom templates in those files 
   that are making the bug behavior more likely.  Working with the files on a 
   separate computer will indicate whether the bug is specific to the files or 
   the system.  If the problem proves to be based on the files, saving them as 
   a native .odf format before working with them might solve the problem.
2. In a standard mouse, an electrical or mechanical malfunction in the mouse 
   buttons can cause a sporadic clicking that is not obvious to a user.  
   Alternatively, might be related to advanced features of non-standard 
   pointing devices, like buttons for copying and pasting.  Try changing the 
   mouse used while working with Impress to see if it resolves the issue.
3. The behavior might be due to a corrupted installation of AOO.  The import 
   functionality might be disrupted, leading to odd issues when working with 
   imported files.  Uninstalling and then reinstalling AOO might repair this 
   issue.

I have attached the .odf and .ppt files used for replicating the duplication
issue mentioned above.
