Title: removing items from the call to six.iteritems

When using the GTK backend, and calling the save dialog (click on save button)

```
Traceback (most recent call last):
File "/home/fariza/workspace/matplotlib/lib/matplotlib/backends/backend_gtk.py", line 752, in save_figure
chooser = self.get_filechooser()
File "/home/fariza/workspace/matplotlib/lib/matplotlib/backends/backend_gtk.py", line 747, in get_filechooser
default_filetype=self.canvas.get_default_filetype())
File "/home/fariza/workspace/matplotlib/lib/matplotlib/backends/backend_gtk.py", line 835, in __init__
self.sorted_filetypes = list(six.iteritems(filetypes.items))
File "/usr/lib/python2.7/dist-packages/six.py", line 254, in iteritems
return iter(getattr(d, _iteritems)())
AttributeError: 'builtin_function_or_method' object has no attribute 'iteritems'
```

Removing the items from the filetypes fixes the problem
