Bzr checkout error

I was trying to clone the keystone package using the given bzr command.

bzr branch lp:ubuntu/trusty/keystone`

However, I got the following error:

bzr: ERROR: Revision {}
 not present in "Graph(StackedParentsProvider
    (bzrlib.repository._LazyListJoin(([CachingParentsProvider(CallableToParentsProviderAdapter(<bound method
  CHKInventoryRepository._get_parent_map_no_fallbacks of
  ('')>))], []))))".

A bit of googling lead me to this bug

which has a workaround..

bzr -Olaunchpad.packaging_verbosity=off branch lp:ubuntu/trusty/keystone

The above command worked flawlessly!
