Re: [matplotlib-devel] reimplemented legend class

[Darren D. <dsd...@gm...>]

I think something broke with the recent changes to legend. For example, in
ipython -pylab:

plot([1,2,3,4],label='test')
legend(loc=(.1, .5))

ERROR: An unexpected error occurred while tokenizing input
The following traceback may be corrupted or invalid
The error message is: ('EOF in multi-line statement', (185, 0))
