Re: Gtk2::SimpleList crashes

Originally, I tried to find a way to delete all values matching certain criteria from a Gtk2::SimpleList (which always crashed). Eventually, I found, that I don't
have to get fancy to cause that crash - the following will do it:

   my @data= {$slist->{data}};
   @{$slist->{data}}= data;

Gtk-CRITICAL **: gtk_list_store_get_value: assertion `VALID_ITER (iter, list_store)' failed at /usr/lib/perl5/Gtk2/ line 248, <F> line 35. GLib-CRITICAL **: g_hash_table_lookup: assertion `hash_table != NULL' failed at /usr/lib/perl5/Gtk2/ line 248, <F> line 35.
Segmentation fault

Can anybody tell me what's wrong with that code snippet?
Is there any workaround?

Can you post a script and your software versions? I can't reproduce on my (rather ancient) system with this:

#!/usr/bin/perl -w

use strict;
use Gtk2 -init;
use Gtk2::SimpleList;

my $slist = Gtk2::SimpleList->new ('Stuff' => 'text');

@{ $slist->{data} } = qw(one two three four five six seven);

my @data = @{ $slist->{data} };
@{ $slist->{data} } = @data;

print "Gtk2::VERSION              $Gtk2::VERSION\n";
print "Gtk2::SimpleList::VERSION  $Gtk2::SimpleList::VERSION\n";
print "Gtk2->GET_VERSION_INFO ".join(".",Gtk2- >GET_VERSION_INFO)."\n"; print "Gtk2->get_version_info ".join(".",Gtk2- >get_version_info)."\n";


Gtk2::VERSION              1.080
Gtk2::SimpleList::VERSION  0.15
Gtk2->GET_VERSION_INFO     2.4.0
Gtk2->get_version_info     2.4.14

Y: That's not funny.
Z: (silent)
Y: Is that funny?
Z: (nods)
Y: Then why didn't you laugh?
Z: Sometimes, whenever it's funny, I don't laugh.  But sometimes, I do.
Y: When is it funny?
Z: Whenever you say "poop" and "fart" and "pee" and "butt," I laugh.
Y: Oh, okay.
