Question

Most of the information is here: http://pastebin.com/VE6dhUkf

But the general error is:

Odd number of elements in hash assignment at /usr/share/perl5/Curses/UI/Container.pm line 72.
Can't use string ("Gino.Francescutti@xx") as an ARRAY ref while "strict refs" in use at /usr/share/perl5/Curses/UI/Listbox.pm line 264.

Note: The “Can’t use string (“Gino.Francescutti@xx”)” Doesn’t contain the full email, only partial.

Answer 1

I’m guessing that you’re mixing up your arrays and array-refs. You have this:

my $listbox; $listbox = $win1->add(
    'list',
    'Listbox',
    -values => @marray,
    -lables => $lhash,
    -onchange => sub { exit($_[0]->get)}
);

Notice the -values => @marray? That should be -values => \@marray. From the fine manual:

my $listbox = $win->add(
    'mylistbox', 'Listbox',
    -values    => [1, 2, 3],
    #...
);

That mixup doesn’t directly point to your error message but it could sufficiently mess up what $win->add is seeing and confuse it enough to cause the error you’re seeing as a side effect.
