Submit Bug?

Question

Doesn't seem to be any easy place to just submit a bug report, so I thought I would just post it here thinking a moderator would submit it for me.  I found an unusual flaw while working with images in Illustrator.  Wondering if everyone else sees the same as I do.  If you follow these steps exactly, you should see what we see.
1) Create an image file (RGB, CMYK or Grayscale, doesn't matter), and save it (PSD or TIFF, doesn't matter).
2) Create a new CMYK or RGB document in Illustrator CS5.
3) On the default layer (normally called "Layer 1"), "Place" the image you created as a "Link".
4) Create a shape and apply it as a clipping mask to the linked image.
5) Create a new layer (by default it's called "Layer 2").
6) In a different location, "Place" the image you created as a "Link" again.
7) Make another shape and apply it as a clipping mask to the second linked image.
8) Save the file as an AI or Illustrator compatible PDF (doesn't matter).
9) Close the file and reopen it in Illustrator.  You'll notice that the artwork appears to be what you created.
10) This time, lock the bottom layer, which should be called "Layer 1".
11) Save the Illustrator file, and close it.
12) Reopen the file and look at your images now.  You'll notice in the "Links" window that there's more images than you originally placed, and at least one of the images is in the wrong location.  You will probably see three images when you had only placed two, and one of the images has a white preview in the "Links" window.
*This is the main flaw of the program.  It only happens when the same image is placed on two different layers and only when the bottom layer is locked.
**After step 12, if you unlock "Layer 1" and save/close the file, the next time you open it, the images appear normal again.  However, it still leaves an extra image in one of the clipping mask, which you can identify from the "Links" window.
***When saving the file as Illustrator PDF and this problem occurs, the document appears accurate when opened in Acrobat, even though it is not correct in Illustrator.
Give it a try and let me know if I'm crazy here!  Must fix this problem!!!!  Thanks all!

Hopefully you can see from these screenshots.
Here is the normal AI file with the links on two separate layers and the layers both unlocked.
This is what happens when we lock the bottom layer, save and close the file, and then reopen the file. 
We are using MAC version, and it occurs on both of our MAC's, two different OS.  We do run Esko Plugins, so if you don't see the same thing we are, I will be submitting a support ticket with them next.  I really appreciate any other confirmations.  Thanks much!
I have this sample file, the image file, and a PDF of my screenshots in a ZIP file which can be downloaded HERE.  Just open the AI file, lock the bottom layer, save and close, then reopen the AI file.
