Bug Description

In Ubuntu 12.04 LTS I get the following error whenever I use the File->Open Containing Folder feature.
  Could not open the containing folder.
  Failed to execute child process "pcmanfm" (Permission denied)

This is precisely bug #864992, but for LXDE instead of Gnome.

 The problem is fixed for LXDE (and presumably KDE and XFCE) by replacing "/usr/bin/nautilus Cx -> sanitized_helper" with the following to /etc/apparmor.d/usr.bin.evince

  /usr/bin/nautilus Cx -> sanitized_helper, #Gnome File Manager
  /usr/bin/pcmanfm Cx -> sanitized_helper, #LXDE File Manager
  /usr/bin/krusader Cx -> sanitized_helper, #KDE File Manager
  /usr/bin/thunar Cx -> sanitized_helper, #XFCE File Manager

(and then running: "sudo /etc/init.d/apparmor reload")

As with bug #864992 the chance of a regression is low, and it should not increase the attack surface in the slightest unless pcmanfm, krusader or thunar were installed (they wouldn't exist in a default Ubuntu install, unless the user manually installed them, in which case the user probably wants to be allowed to use them).
