I have found two issues trying to use the get_text method in vte with python
after apply this patch.

The first is I can't set is_selected as None, the c code can manage it (vte.c
line 6293) but the introspection annotations don't allow this.

Can be solved doing:

- * @is_selected: (scope call): a #VteSelectionFunc callback
+ * @is_selected: (scope call) (allow-none): a #VteSelectionFunc callback

The second issue is more difficult to solve in a proper way:

The attributes parameter is marked as:

- * @attributes: (out) (transfer full) (array) (element-type
Vte.CharAttributes): location for storing text attributes

but if is a out parameter, I can't pass it as a parameter from python, and the
first line using the parameter in the c code is:

line 6298

    if (attributes)
        g_array_set_size (attributes, 0);

Then should be None or a already created GArray.

Right now the application crash when I do:

vte.get_text(None, None)

The only workaround I have found is change:

 - * @attributes: (out) (transfer full) (array) (element-type
Vte.CharAttributes): location for storing text attributes
+ * @attributes: (array) (element-type Vte.CharAttributes): location for
storing text attributes

and calling from python doing:

vte.get_text(None, None, [])

now the application don't crash, but of course the attributes array is not
loaded.

A test case is attached, and a diff to test these changes.
