Should no longer be an issue with python-keyring ≥ 1.2.2 (i.e. the
current version in Saucy).

** No longer affects: ubuntu-dev-tools (Ubuntu)

** Changed in: python-keyring (Ubuntu)
       Status: Confirmed => Fix Released

Title:
  [syncpackage] crashed with AttributeError in get_password():
  'NoneType' object has no attribute 'keyDoesNotExist'

Status in “python-keyring” package in Ubuntu:
  Fix Released

Bug description:
  I've used syncpackage without --bug or --sponsor as recently as
  yesterday with no problems, so I doubt this is a local system issue.
  I do have kwallet set to ask every time if it's OK to give access and
  it didn't even ask.  It was like it doesn't even wait for an answer.
  In any case, this error should be caught and a more helpful, user
  friendly error message provided.

  $ syncpackage --bug=1027775 --sponsor=logan python-pylibacl
