Comment 5 for bug 538404

The problems seems to be that webkit doesn't expose the button properly.

<input type="button" id="button_install"
          class="action_button"
          alt="Install - Free"
          value="Install - Free"
          onclick='action_button_clicked()'
      />
      <label for="button_install" id="install_info">
        <img id="installed_icon" src="file:/usr/share/software-center/icons/software-center-installed.png"/>
      </label>
