Bug description:
  [Test Case]
  1) Install one of the affected languages
  2) Make it the primary language
  3) In a terminal run '/usr/lib/ubuntu-release-upgrader/check-new-release-gtk' for saucy
     In a terminal run '/usr/lib/update-manager/check-new-release-gtk -d' for precise
  4) Observe a Traceback ending in a "ValueError: incomplete format" in precise the traceback says "ValueError: unsupported format character"

  With the package from -proposed you should not see a Traceback, but
  rather a notification window about the new release of Ubuntu.

  The error bucket at
  https://errors.ubuntu.com/problem/50c8f7b892dd75b531ac7d68a07ec11541387013
  contains the following traceback.

  Traceback (most recent call last):
    File "/usr/lib/ubuntu-release-upgrader/check-new-release-gtk", line 113, in new_dist_available
      self.window_main.set_title(_("Ubuntu %(version)s Upgrade Available") % {'version': new_dist.version})
  ValueError: incomplete format

  This is due to a bad translation for the Croatian (hr) language.

  https://translations.launchpad.net/ubuntu/saucy/+source/ubuntu-
  release-upgrader/+pots/ubuntu-release-
  upgrader/hr/+translate?batch=10&show=all&search=Upgrade+Available

  "Dostupna nadogradnja Ubuntu %(version)"

  Notice the missing s after version. This is causing check-new-release-
  gtk to fail to notify users of a new release.
