objgraph docs/uncollectable.txt test fails with Python 3.4

Imported from Debian bug http://bugs.debian.org/734586:

Package: objgraph
Version: 1.7.2-2

Hello,

objgraph's test suite fails with python 3.4:

| $ python3.4 tests.py
| ..........F/usr/lib/python3.4/imp.py:32: PendingDeprecationWarning: the imp module is deprecated in favour of importlib; see the module's documentation for alternative uses
| PendingDeprecationWarning)
| .

It works fine with 2.7 and 3.3, so apparently Python 3.4 has some
changes in its garbage collection which fail that test?

Keeping at "normal" for now as Python 3.4 is still in experimental.
This will become serious (FTBFS) as soon as 3.4 becomes a supported
version in sid.

Thanks for considering,

Martin
