[matplotlib-devel] unicodeescape traceback on build of latest master in IPython

[Joel B. M. <jm...@ga...>]

I'm getting a unicodeescape error importing matplotlib in the IPython 
notebook interface.  The traceback is shown below.  Annotate states that 
https://github.com/matplotlib/matplotlib/commit/bd71341ff645e1e4eb7470a5d2a5541e73bf6d5f 
introduced the changes to __init__.py which appears to have instigated 
the error.  I was able to import matplotlib 1.3.1 in the IPython 
notebook.  This traceback is appearing for me in both IPython 1.0.0 and 
1.1.0.  I'm on win32 32-bit.  I would appreciate feedback on whether 
this is a real regression or something on my system.

import matplotlib
