Tkinter: canvas itemconfigure bug
Consider following code:
-- tkbug.py ---
from Tkinter import *
root = Tk()
canvas = Canvas(root)
text = "sample text with spaces"
id = canvas.create_text(0, 0, text=text)
text2 = canvas.itemconfigure(id)['text'][-1]
print text
print text2
--- eof ---
This toy prints:
sample text with spaces
('sample', 'text', 'with', 'spaces')
The returned value is not a string -- Tk returns the same
string as passed on creating item, but Tkinter split it.
To fix this problem, internal method '_configure' have
to be changed a bit:

 cnf[x[0][1:]] = (x[0][1:],) + x[1:]
 return cnf
 if type(cnf) is StringType:

Maybe better/faster way is to provide Canvas method, that
return a 'text' property for text items:
---
def get_text(self, text_id):
	try:
		r = self.tk.call(self._w, 'itemconfigure', text_id, '-text')
		return self.tk.splitlist(r)[-1]
	except TclError:
		return ''
