Bear with me, I have the same difficulties as you to grok your code ;-) 
    -textvariable => \$::cini_global->{trickle}->{email_template_file}

[download]

Is this a reference? is $cini_global a hash reference? Is the value that falls out the dereferencing chain a reference? 

$::cini_global->{trickle}->{email_template_file} = $self->{_nb}->getOp
+enFile(-filetypes => \@types );

[download]
is $self->{_nb}->getOpenFile(-filetypes => \@types ) returning a reference? Are you passing a value or a reference via that assignment?

Having these questions answered, the solution to the problem may be simple ;-)

_($_=" "x(1<<5)."?\n".q·/)Oo.  G°\        /
