r85770 adds the parentid to list=deletedrevs, unfortunately that field is always NULL (bug 28553). At the moment a parentid="0" is added, but a parentid of 0 indicated the last revision of that page (in prop=revisions), so adding a 0 for all revisions is a bad idea. prop=revisions makes a is_null() check. Please also make the null check in list=deletedrevs. Thanks.
