Code review comment for lp:~xnox/ubuntuone-client/fix-apport

Apport in quantal and running runs as python3.
First the approt hook fails with dirspec import error, as python3-dirspec is not installed.
In python3, dirspec returns bytes and os.path.join doesn't allow mixing bytes and strings in path components.

$ python3 -c "import os; os.path.join(b'somebytes', 'somestring')"
Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/usr/lib/python3.3/posixpath.py", line 92, in join
    "components.") from None
TypeError: Can't mix strings and bytes in path components.

This is to fix apport hook, cause currently apport hook fails in Quantal & Raring. Thus no bug reports filed from quantal/raring have any data that is meant to be collected by this hook.
