             Bug #: 5791
           Summary: Robust handling of deleted biblios/authorities
    Classification: Unclassified
 Change sponsored?: ---
           Product: Koha
           Version: master
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P5
         Component: Architecture, internals, and plumbing

When a biblio/authority is deleted, and for some reason one tries to access it
via a (saved) URL (as when you reach the link via log viewer) koha presents the
user a very ugly system error:

Software error:

Can't call method "field" on an undefined value at
/home/tomas/Work/koha/devel/koha-community-3.2.x/authorities/detail.pl line 82.

This is correctly handled for patrons, presenting a convenient "This patron
does not exist." A similar approach should be implemented for biblios AND
authorities.
