Title:
  software-properties-gtk crashed with DBusException in call_blocking():
  com.ubuntu.SoftwareProperties.PermissionDeniedByPolicy:
  com.ubuntu.softwareproperties.applychanges

Status in “software-properties” package in Ubuntu:
  Fix Released
Status in “software-properties” source package in Precise:
  Fix Released

Bug description:
  [Test Case]
  1. install the version from -proposed
  2. launch software-properties
  3. do any action that requires an authentification and cancel it
  -> you should see a warning showing on the command line (if you launched it)
  -> whoopsie shouldn't trigger that a crash happened.

  [Regression Potential]
  None, as it's just wrapping the crash in a try/except clause.

  This is reproducible by launching software-properties-gtk as any user
  that is not an admin, or from any session where the user can't be
  verified to be an admin via policykit - including when the user hits
  'cancel' in the authentication dialog. We should suppress these
  exceptions so they don't show up as crashes on the desktop.
