We never got around to this while 14.04 was the current LTS. It's fixed
in 16.04 LTS. Marking wontfix as it seems unlikely to be a priority
now.

Bug description:
The 2.5.0-5ubuntu1 upload in proposed includes the following change:
* python-protobuf: switch back to the pure Python implementation, as
upstream appears to no longer be maintaining the current C++ based Python
binding. See the following upstream issues for details:
- https://code.google.com/p/protobuf/issues/detail?id=434
- https://code.google.com/p/protobuf/issues/detail?id=503
However, the cpp_message.py is still included, and tries to import the
C++ based module which no longer exists, which results in the
following failure in the ubuntuone-storage-protocol tests:

It seems like this python module should instead issue a
DeprecationWarning and fall back to using the pure python
implementation, whilst code which uses the cpp module in some way,
transitions over to the pure python implementation.
