Here is a complete list of all modules required to run PerlPanel:

Digest::MD5
File::Basename
Gnome2::VFS
Gnome2::Wnck
Gtk2
Gtk2::GladeXML
Gtk2::Helper
Gtk2::SimpleList
Gtk2::TrayManager
Locale::gettext
URI::Escape
XML::Parser
XML::Simple

This is an internal warning from libwnck, there's nothing we can do to
suppress it.

The Name() method is from PerlPanel::DesktopEntry, and is probably
caused because there's a badly formatted .desktop file somewhere in your
applications: tree. Open GnomeMenu.pm and change line 26 from

$PerlPanel::DesktopEntry::SILENT = 1;

to

$PerlPanel::DesktopEntry::SILENT = 0;

and DeskopEntry.pm should show a warning when it comes across an invalid
file.

If a Perl program segfaults, then it's a problem with the underlying C
bindings, or Perl itself - an error in a Perl program should result in a
Perlish error message. Check your .perlpanelrc, and look for any lines
that look like this:

<applets>Launcher::d67b49045c3d3e7faab9e07905441fd1</applets>

This applet uses the .desktop file in
$HOME/.launchers/d67b49045c3d3e7faab9e07905441fd1.desktop - if you email
me your .perlpanelrc and this file, I will test them myself.

Gavin.
