Guake Terminal 3.4.0
Python 3.6.5
Gentoo Linux

I just upgraded Guake from 3.3.2 to 3.4.0 and it is now failing to start because it can't load the GLib schema.

```
Guake not running, starting it

I tracked it down to ab7b44ab346803f5846eb2959011ffe2270b8153. If I undo this change, guake will start.

Broken:
```python
>>> d = os.path.dirname(os.path.dirname(sys.modules["guake"].__file__))
>>> p = os.path.basename(os.path.abspath(os.path.join(d, "..")))
>>> print('%s\n%s' % (d, p))
/usr/lib64/python3.6/site-packages
python3.6
```
Works:
``` python
>>> d = os.path.dirname(sys.modules["guake"].__file__)
>>> p = os.path.basename(os.path.abspath(os.path.join(d, "..")))
>>> print('%s\n%s' % (d, p))
/usr/lib64/python3.6/site-packages/guake
site-packages
```

Was the intended change perhaps to change the next line from `os.path.abspath(os.path.join(d, ".."))` to `os.path.dirname(d)`?
