Bug description:
  I tried to unpack a tar.gz and just after I got a warning that the
  file wasn't a tar.gz my screen went black and I saw this message:

  Dec 16 11:53:59 tim-thinkpad kernel: [11199.075040] Valid eCryptfs headers not found in file header region or xattr region
  Dec 16 11:53:59 tim-thinkpad kernel: [11199.075045] Either the lower file is not in a valid eCryptfs format, or the key could not be retrieved. Plaintext passthrough mode is not enabled; returning -EIO
