When attempting to search for new items to add to a batch, a search with
results returns:

Can't use an undefined value as a HASH reference at
/usr/share/koha/intranet/cgi-bin/labels/label-item-search.pl line 129

Similarly, if one can get to manage a created batch, attempting to edit a batch
will result in 

Can't use an undefined value as a HASH reference at
/usr/share/koha/lib/C4/Creators/Lib.pm line 321

This seems to be caused by some compilations of Perl not allowing a hash to be
declared and assigned on the same line.  The offending lines of code are:

my $item_data->{'_item_number'} = $item_results->{$item}->{'itemnumber'}; (from
label-item-search.pl)

my $label_summary->{'_label_number'} = $label_number; (in C4/Creators/Lib.pm).

Splitting the declaration and assignment into two lines fixes the problem.

my $item_data;
$item_data->{'_item_number'} = $item_results->{$item}->{'itemnumber'}; (from
label-item-search.pl)

my $label_summary;
$label_summary->{'_label_number'} = $label_number; (in C4/Creators/Lib.pm).
