I think you found a really stupid bug :)

You could try escaping the string as per the trace from http://www.tkdocs.com/tutorial/onepage.html 

#!/usr/bin/perl --

use Tkx;
$Tkx::TRACE = 64;
Tkx::package_require('tile');
my $mw = Tkx::widget->new(".");

# example bug : new_tk__listbox
( $lb = $mw->new_listbox( -height => 5 ) )
  ->g_grid( -column => 0, -row => 0, -sticky => "nwes" );
(
    $s = $mw->new_ttk__scrollbar(
        -command => [ $lb, "yview" ],
        -orient  => "vertical"
    )
)->g_grid( -column => 1, -row => 0, -sticky => "ns" );
$lb->configure( -yscrollcommand => [ $s, "set" ] );
(
    $mw->new_ttk__label(
        -text   => "Status message here",
        -anchor => "w"
    )
)->g_grid( -column => 0, -row => 1, -sticky => "we" );
( $mw->new_ttk__sizegrip )->g_grid( -column => 1, -row => 1, -sticky =
+> "se" );
$mw->g_grid_columnconfigure( 0, -weight => 1 );
$mw->g_grid_rowconfigure( 0, -weight => 1 );

for ( $i = 0 ; $i < 100 ; $i++ ) {
#~     $lb->insert( "end", "Line " . $i . " of 100" );
    $lb->insert( "end", "Line " . $i . " of {100}" );
}

Tkx::MainLoop();
