Comment(by runa):

 I then covered a second use case:

  * User boots Debian 6 (Squeeze)
  * User logs in as a normal user (i.e. not admin)
  * User attaches an external drive
  * Using the GUI: user copies the Tor Browser Bundle from the external
 drive to the home dir
  * Using the GUI: user extracts the Tor Browser Bundle
  * Using the GUI: user runs the Tor Browser Bundle by clicking on the
 ''start-tor-browser'' file
  * User browses a few sites in the Tor Browser
  * User closes the Tor Browser window and clicks the ''Exit''-button in
 Vidalia
  * Using the GUI: user deletes the Tor Browser package and archive
  * Using the GUI: user empties the trash can
  * User shuts down Debian 6 (Squeeze)

 I started with a fresh install of Debian 6 (Squeeze). The file
 ''debian_changed_files2.txt'' contains a list of 58 files which were
 either created or modified between the time I booted Debian, used the Tor
 Browser Bundle, and shut the system down.

 Most files are files you expect to see change when using Debian. However,
 there are a small number of files which also contain traces of the Tor
 Browser Bundle and/or show that an external device was attached.

 '''/home/runa/.recently-used.xbel''': Created by the system. This file
 contains the filename of the Tor Browser Bundle tarball, ''tor-browser-
 gnu-linux-x86_64-2.3.25-5-dev-en-US.tar.gz'', as well as the time and date
 it was added, modified, and visited. I have created #8706 for this issue.

 '''/home/runa/.xsession-errors''': Modified by the system. This file
 contains the following string: ''Window manager warning: Buggy client sent
 a _NET_ACTIVE_WINDOW message with a timestamp of 0 for 0x3800089 (Tor
 Browse)''. It is worth noting that a file named ''.xsession-errors.old''
 could also exist. I have created #8696 for this issue.

 '''/home/runa/.local/share/gvfs-metadata/home-c0ca7993.log''': Created by
 the system. This file contains lines indicating that the Tor Browser
 Bundle was deleted, such as ''/.local/share/Trash/expunged/3864782161
 /start-tor-browser'' and
 ''/.local/share/Trash/expunged/3864782161/App/tor''. I have created #8707
 for this issue.

 '''/home/runa/.gconf/apps/nautilus/desktop-
 metadata/THA@46@volume/%gconf.xml''': Created by the system. No trace
 found in the file, but the filename indicates that a device was mounted
 (in this case an external drive).

 '''/var/log/daemon.log''', '''/var/log/syslog''', '''/var/log/kern.log''',
 '''/var/log/messages''': contains information about attached devices. I
 had an external drive attached to the virtual machine, so these files
 contain lines such as ''Mounted /dev/sdb1 (Read-Write, label âTHAâ, NTFS
 3.1)'' and ''Initializing USB Mass Storage driverâ''.
