Prolems with liststore insert_with valuesv

[Mike Martin <redtux1 gmail com>]

Hi

I am trying to use insert_with_valuesv to populate a liststore as follws

my ($resultmodel,$result)=@_;
    no strict 'refs';
    #print $resultmodel;
    my @cols=0 .. scalar @{$result->[0]} -1;

    foreach my $f (@{$result}){

    my $iter=$resultmodel->insert_with_valuesv(-1,\@cols,$f);
}

$result is an arrayref passed to the sub and resultmodel is the liststore

Unfortunately I am getting 'Cannot convert arbitrary SV to GValue' with I assume $f which is an array ref

As far as I can see this should work

Any ideeas what I am doing wrong?
