Comment 1 for bug 291850

For progress pulsate, mine is still working in intrepid, but not for progress bar.

May be you could try to add redirection in your script, so, from:

wget -cv "http://fpdownload.macromedia.com/get/flashplayer/current/install_flash_player_10_linux.tar.gz" |zenity --progress --pulsate --auto-close --title="teste da barra de progresso" --text "Download de :\n\thttp://fpdownload.macromedia.com/get/flashplayer/current/install_flash_player_10_linux.tar.gz\nDownload para :\n\tinstall_flash_player_10_linux.tar.gz..."

change it to:

wget -cv "http://fpdownload.macromedia.com/get/flashplayer/current/install_flash_player_10_linux.tar.gz" 2>&1 | zenity --progress --pulsate --auto-close --title="teste da barra de progresso" --text "Download de :\n\thttp://fpdownload.macromedia.com/get/flashplayer/current/install_flash_player_10_linux.tar.gz\nDownload para :\n\tinstall_flash_player_10_linux.tar.gz..."

I have confirmed progress pulsate works if you add redirection.
