This patch fixes all the occurrences, staff and OPAC. The problem only happens on some versions of Chrome.
TO TEST:
-set up a new list with a few items
-go to /cgi-bin/koha/virtualshelves/shelves.pl and view that list.
-Click 'Print List' in Chrome.
-The tab opens but immediately closes itself.
-Apply patch and clear cache
-Try again, the print dialouge remains open

-Go to cgi-bin/koha/sco/sco-main.pl in Chrome, make sure you can finish and print successfully
-In the staff client in Chrome makes sure printing works in the following areas:
    1. /cgi-bin/koha/circ/circulation.pl Print Slip and Print Quick Slip
    2. /cgi-bin/koha/members/boraccount.pl Make a payment and make sure you can print the invoice
    3. cgi-bin/koha/labels/spinelabel-home.pl Make a quick spine label in Chrome and make sure that prints.
