Hi,
Using the new IPython with --pylab option:
Creating a simple plot via
plt.plot(range(10))
then typing in the shell for example:
plt.plot? and getting the help blocks the figure. Is this a known
issue? I don't recall seeing this behavior in the previous IPython.
matplotlib.__version__
'1.1.0'
using Qt4Agg also confirmed with WXAgg

I was worried about accepting the changes without a Mac to test them on, 
and hoping that Michiel de Hoon (the Mac backend author) would have some 
comments. Maybe we can convince one of the other developers on this 
list who has a Mac to have a look.

Can you file an issue for this in the matplotlib-py3 github project? 
I'm busy getting the matplotlib 1.1.x release finished up at the moment, 
and don't have a working environment for Python 3 right now. I'd hate 
for this bug to fall through the cracks.
Cheers,
Mike

Hi everyone
I've found a few problems in the current matplotlib-py3 branch in the
_macosx.c code. I've put the fixes in a fork here:
 https://github.com/grahame/matplotlib-py3
I saw a pull request for a similar patch with a lot of comments that
seems to be stuck, so I thought I'd ask here what to do. It'd be great
to get the master branch working on Mac.
Another thing - I think I've found a str/bytes bug which I can't
figure it out. I've attached the code, if I run it on my machine I get
this output:
Traceback (most recent call last):
 File "crash.py", line 24, in <module>
 fig.canvas.print_figure(open('test.png', 'wb'), bbox_inches='tight')
 File "/opt/shrubbery/lib/python3.2/site-packages/matplotlib/backend_bases.py",
line 1951, in print_figure
 bbox_inches = self.figure.get_tightbbox(renderer)
 File "/opt/shrubbery/lib/python3.2/site-packages/matplotlib/figure.py",
line 1292, in get_tightbbox
 for ax in self.axes:
 File "/opt/shrubbery/lib/python3.2/site-packages/matplotlib/figure.py",
line 290, in _get_axes
 return self._axstack.as_list()
 File "/opt/shrubbery/lib/python3.2/site-packages/matplotlib/figure.py",
line 59, in as_list
 ia_list = [a for k, a in self._elements]
 File "/opt/shrubbery/lib/python3.2/site-packages/matplotlib/figure.py",
line 59, in <listcomp>
 ia_list = [a for k, a in self._elements]
TypeError: string argument expected, got 'bytes'
It's definitely something to do with the bbox_inches='tight' argument,
if I take that out everything works. Using the debugger I can't see
anything in any stack frame that explains the traceback - really odd!
Thanks
