attic fails with ImportError on startup

[Pauli Virtanen]

Starting attic fails with

$ attic
Traceback (most recent call last):
  File "/usr/bin/attic", line 2, in <module>
    from attic.archiver import main
  File "/usr/lib/python3/dist-packages/attic/archiver.py", line 10, in <module>
    from attic.archive import Archive
  File "/usr/lib/python3/dist-packages/attic/archive.py", line 12, in <module>
    from attic.chunker import chunkify
ImportError: No module named 'attic.chunker'

The reason is that /usr/bin/attic starts with "#!/usr/bin/python3", which on Ubuntu trusty is alias for python 3.4, whereas the attic package 0.10-1 contains compiled modules only for Python 3.3.

The upstream developer is recommending using the Utopic version of Attic as a workaround for this bug.

As far as I can see the Utopic version should have dependencies satisfied in Trusty.
