Thanks much.

Thanks John!! We are able to replicate the issue. We have logged the bug for the same.

Another common use-case for this: 

External editors and plugins produce new versions named photo-1.tif, photo-2.tif, etc. Sometimes a user wants to make several different versions with different settings for comparison, so she renames the files to have more useful names, e.g. photo-large.tif, photo-small.tif, etc.

This was precisely the scenario in which I tripped over the bug, using my Apply LUT plugin (well, actually a customer reported it to me).

This use-case also occurs with Edit In Photoshop. LR chokes on this, but rather than corrupting the catalog, it hangs: https://feedback.photoshop.com/photoshop_family/topics/lightroom-edit-in-photoshop-hangs-after-renaming-a-previous-edited-version

Importing a file with the same name as the original name of a file that was renamed can corrupt the catalog, producing two photos in the catalog with the same filename. I first noticed this bug with my Apply LUT plugin, and it might be related to this person's corruption:

To reproduce:

1. Create a folder "f".

2. Place "x.jpg" into "a" and import it using Add.

3. In Finder, make a copy of "x.jpg" in "a" called "x-a.jpg". 

4. In LR, select "f" in the Folders panel and do Synchronize with the import option Add. There should now be two photos appearing in "f" in the catalog:



5. In the Metadata > Default panel, rename "x-a.jpg" to "x-b.jpg".

6. In Finder, make a copy of "x.jpg" named "x-a.jpg".

7. In LR, synchronize "f" again with the import option Add. There are now three photos shown in "f", with two named "x-b.jpg":



Perhaps the import logic is using the "original filename" rather than the "current filename" when determining duplicates?

8. Select both copies of "x-b.jpg" and hit Delete, choosing Delete From Disk.  This error results:



The two thumbnails are now marked as missing in Library view.  Finder shows "x-b.jpg" as deleted, while "x-a.jpg" is still present.

Tested on LR 8.2.1 / Mac OS 10.14.3.

It might be the case that “Import” using the import dialog instead of using “sync” to import MAY not have this issue. I didn’t try that.

Exactly...and if you think about it, there are actually a number of scenarios where you could end up with the same original filename being imported  - using multiple cards on the same shoot, using multiple camera bodies with numbering set the same way, etc.  My Canon will start the numbering sequence over if a new folder is created on the card, so the same card could even have the same filename on it in different folders.

it's not affecting my workflow at all, but I am still curious about the restart.  That could be mitigating/hiding the problem for folks that aren't importing multiple times in the same session.
