Have only tried this on Python 2.7

To reproduce:

from Tkinter import *
import ttk

```py
root = Tk()
tree = ttk.Treeview(root)

id = tree.insert('' , 'end', text='foo', tag='bar')
print tree.tag_has('bar', item=id)
# ^ this works..
print tree.tag_has('baz', item=id)
# ^ .. and this..
print tree.tag_has('bar')
# ^ .. this doesn't.

...
self.tk.call(self._w, "tag", "has", tagname, item))
TypeError: must be string, not tuple

Possibly introduced by bpo-20072.

Removing the self.tk.getboolean() wrapper in tag_has() appears to fix things.

Thank your for your report David.

Here is a patch which fixes the bug and adds tests for Treeview.tag_has().
