Tk ItemStyle problem on linux

greenFox has asked for the wisdom of the Perl Monks concerning the following question:

Hi, the code below runs fine on my active state 5.8 installation at work but barfs with the error:
"at /usr/local/lib/perl5/site_perl/5.8.0/i686-linux/Tk/ItemStyle.pm line 21."
under RH9.0, Perl 5.8.0 (fresh install from source) and Tk804.024. Interestingly if I only specify the background colour style it works fine. Any-one have any clues? Thanks.

#!/usr/bin/perl -w

use strict;

use Tk;
use Tk::HList;
use Tk::ItemStyle;
use Tk::Label;

my $mw = MainWindow->new();
my $label = $mw->Label(-width=>15);
my $hlist = $mw->HList(
  -itemtype    => 'text',
  -separator  => '/',
  -selectmode => 'single',
  -browsecmd  => sub {
      my $file = shift;
      $label->configure(-text=>$file);
   }
);


my %priorities = (     
  1 => { text => 'Highest', colour => 'red'       },
  2 => { text => 'High',    colour => 'orange'    },
  3 => { text => 'Medium',  colour => 'darkgreen' },
  4 => { text => 'Low',     colour => 'blue'      },
);

for my $int (1..4){
  $priorities{$int}->{style} = $hlist->ItemStyle('text',
    -foreground       => $priorities{$int}->{colour},
    -background       => 'white',
    -selectbackground => '#0A246A',
    -selectforeground => 'white',
  );
}

foreach ( qw(/ /home /home/ioi /home/foo /usr /usr/lib) ) {
  $hlist->add($_, -text=>$_, -style=>$priorities{1}->{style});
}

$hlist->pack;
$label->pack;
MainLoop;

Most of the code above is from the Tk::HList manapge, I used it to work up the test case :)

Following myself up here... the behaviour I am seeing appears to be related to a known problem as reported on the ptk mailing list here and acknowledged here by Nick Ing-Simmons. I will submit a further bug report and update this node when I have more information Update: I have a patchset to test- http://www.cpan.org/modules/by-authors/id/L/LU/LUSOL/Tk804.024.patches-0.1.tar.gz gratefull thanks to Slaven Rezic, will further update when I have had a chance to test the patchset. Update: Applied the patchset all is now working as expected. Thanks again to Slaven and also to Steve Lidie and any-one else who put work into the patchset. -- Do not seek to follow in the footsteps of the wise. Seek what they sought. -Basho	[reply]

`"at /usr/local/lib/perl5/site_perl/5.8.0/i686-linux/Tk/ItemStyle.pm line 21."` tells us where the exception occurred, but doesn't tell us what the exception was. If you include the rest of the exception we may be able to help you figure out what's going wrong.	[reply] [d/l]

Yes. I tested it on perl 5.8.0 on two gentoo systems and a Debian (testing/unstable) system, all running perl 5.8.0. It seems to work fine, no errors. Is your original perl install from RPMs still functional? Have you tested with that build?	[reply]
