>Subject: [PATCH] Bug 37425: Check for existence of biblio object before
> fetching cover images
>
>This patch simply adds a conditional to ensure the biblio object has been retrieved and assumes no cover images otherwise
>
>To test:
> 1 - Enable system preference LocalCoverImages
> 2 - Perform a search in staff interface
> 3 - Find the biblionumebr for one of the results and delete it via the SQL backend:
>     DELETE FROM biblio WHERE biblionumber=3;
> 4 - Search again.
> 5 - KO!
>     Can't call method "cover_images" on an undefined value at /usr/share/koha/intranet/cgi-bin/catalogue/search.pl line 671.
> 6 - Reindex, confirm error is gone
> 7 - Apply patch
> 8 - Search again
> 9 - Delete a record from the results via SQL
>10 - Reload and confirm no error
>11 - Reindex and repeat search and confirm no error
