            Bug ID: 20829
           Summary: 'Link to host item' gives internal server error for
                    invalid item barcode
 Change sponsored?: ---
           Product: Koha
           Version: master
          Hardware: All
                OS: All
            Status: NEW
          Severity: normal
          Priority: P5 - low
         Component: Cataloging
          Assignee: koha-bugs at lists.koha-community.org

To test:
- Turn on EasyAnalyticalRecords
- Go to a detail page
- Edit > Link to host item
- Enter an invalid barcode (some additional whitespace around a copied one will
do it) 
- Verify it explodes into an internal server error
