Hi!

After installing matplotlib 0.99.0 (over 0.98.6) I started to get the 
following exceptions while checking hitlist:

Traceback (most recent call last):
  File "C:\Python26\Lib\site-packages\matplotlib\artist.py", line 231, 
in hitlist
    hascursor,info = self.contains(event)
  File "C:\Python26\Lib\site-packages\matplotlib\lines.py", line 286, in 
contains
    path, affine = self._transformed_path.get_transformed_path_and_affine()
AttributeError: 'NoneType' object has no attribute 
'get_transformed_path_and_affine'
while checking <class 'matplotlib.lines.Line2D'>
...(several times the same exception for one mouse event)

The exception is produced with 'motion_notify_event' when trying to get 
the hitlist.

How could I solve this problem?

Thanks
Romi
