'module' object has no attribute 'instancemethod'

Out of the blue, I started getting this messages while plotting with MPL 1.2.1:

···

========================================
Traceback (most recent call last):

File “C:\Python27\lib\site-packages\matplotlib\backends\backend_qt4.py”, line 244, in mouseMoveEvent
FigureCanvasBase.motion_notify_event( self, x, y )
File “C:\Python27\lib\site-packages\matplotlib\backend_bases.py”, line 1724, in motion_notify_event

self.callbacks.process(s, event)

File “C:\Python27\lib\site-packages\matplotlib\cbook.py”, line 343, in process

File “C:\Python27\lib\site-packages\matplotlib\cbook.py”, line 215, in call

mtd = new.instancemethod(self.func, self.inst(), self.klass)

AttributeError: ‘module’ object has no attribute ‘instancemethod’

I didn’t install any new package or change my Python installation in any way, which makes this hard for me to solve. The message appears when I move my mouse pointer inside plot window. I first removed matplotlibrc from my “home” folder, and it happens again regardless backend changed this way from wx to tk (which is default). I set backend to qt4 also, but it’s just the same.

Any ideas?

There is likely a `new` module in sys.path that shadows Python's builtin new module. Add a `import new;print(new.__file__)` statement at the top of your script. It should output 'X:\\Python27\\lib\\new.pyc'
