To re-create:

1) Create a text file containing duplicate barcodes

Here's a quick way to do that, substitute INSTANCE for the instance name of
your test server:

sudo koha-mysql INSTANCE <<< "select barcode from items where barcode is not
null limit 3" | sed '1d;p' > /tmp/dup_barcodes.txt

2) Go to Home › Tools › Batch item deletion
3) Click 'Choose File', select the file you created in step 1.
4) Click 'Continue'
5) Note that duplicate items appear in the list of items to batch delete
6) Check 'Delete records if no items remain'
7) This will trigger a software error

Here is the output from the intranet error log:

Note that entering the barcodes via the 'scan items one by one' text box
removes duplicates in the list, so this only causes problems when uploading a
file.

It doesn't matter whether you choose duplicate barcodes or duplicate item
numbers, both trigger the some error.
