Title:
  One time of 128, session is opened incorrectly

Status in “python-secretstorage” package in Ubuntu:
  Fix Released
Status in “python-secretstorage” source package in Trusty:
  Fix Released

Bug description:
  == Impact ==
  Sometimes (one time of 128), the binary representation of common secret is 127 bytes long instead of 128, which makes the session invalid, and encrypting/decrypting produces wrong results (or crashes).

  This will lead to end-user tools (like most tools in ubuntu-dev-tools)
  to be working incorrectly.

  == Test case ==
  This can be easily reproduced by running upstream test suite (for example via autopkgtest) many times.

  == Development fix ==
  Fixed in 2.1.1, which is now in utopic

  == Regression Potential ==
  Two-lines fix, does not cause any regressions
