Aperture does not import all files in folder.

Question

I have a folder with 3460 images.  They are a combination of NEF, TIF, and PSD and xmp files.
When it was finished importing it said it had imported the 3460 images; however, there are only 3278 images showing.
I tried starting a new library, and importing the same folder again.  Again, I got 3278 images.
If I use the Finder and go to the folder, it shows 3496 files; however, 36 of those are .xmp files.
Any idea how I can check to see which files are not importing?  Or what I can do to get these 182 files in Aperture?
Many thanks for any help.

Could be just chasing a ghost, but at least we'll know we don't have to capture it.  Let's do two things to determine how many Images Aperture thinks are in the Library.
1.)
Select the container "Photos" listed near the top of the Library Inspector.
Clear the filter.  (In Browser view, click the magnifying glass icon _inside_ the search field, and select "Show all" from the dropdown menu.)
Deselect all.  ("Edit ▹ Deselect All".)
Expand all Stacks.  ("Stacks ▹ Open all Stacks".)
What does Aperture report in the bottom border of the Browser?  Should be something like "1234 items displayed".
2.)
Close Aperture.
"{option}+{click}" the Aperture Dock icon.  (Hold {option} down until the dialog shows up.)
Select your Library from the list.
What does Aperture report below the list of Libraries (you may have only one Library in the list)?  Should be something like "1234 versions, 1234 originals".
