[Brian Murray]

Hello Dmitry, or anyone else affected,

Accepted python-secretstorage into trusty-proposed. The package will
build now and be available at http://launchpad.net/ubuntu/+source
/python-secretstorage/2.0.0-1ubuntu1.1 in a few hours, and then in the
-proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to
enable and use -proposed.  Your feedback will aid us getting this update
out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, and change the tag
from verification-needed to verification-done. If it does not fix the
bug for you, please add a comment stating that, and change the tag to
verification-failed.  In either case, details of your testing will help
us make a better decision.

Further information regarding the verification process can be found at

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 Committed

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

  https://github.com/mitya57/secretstorage/commit/d55efce2c04b053c

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