[Matplotlib-devel] TclError with TkAgg + matplotlib 1.5.1 + Anaconda/miniconda on OS X 10.11

Hi all,
I'm having issues using TkAgg on matplotlib 1.5.1 from the Anaconda
distribution that I've been unable to get to the bottom of. When trying to
show the plot, I get an exception _tkinter.TclError with the message
"invalid command name "PyAggImagePhoto"" and the plot does not display.
The full gory details are at the end of this message, but in brief to
reproduce (with conda):
$ conda create --yes -n testcase-tkinter-2 python=3.5 matplotlib
$ source activate testcase-tkinter-2
$ python -c "import matplotlib; matplotlib.use('TkAgg'); from matplotlib
import pyplot as plt; plt.plot(1,1); plt.show()"
Displaying the plot gets as far as opening a window, but does not show the
plot. The exception is "_tkinter.TclError: invalid command name
"PyAggImagePhoto""
Based on the warnings emitted (see below), it looks like a library
mismatch of some kind between the system Tk and the Anaconda Tk.
When I reported the issue to the Anaconda maintainers, I was pointed to
this PR: https://github.com/matplotlib/matplotlib/pull/6442 They say that
this will fix the issue, but not until 1.5.2 is released.
My question, I guess, is: will this fix the issue? And will 1.5.2 be
released soon?
Many thanks,

To reproduce the objc warnings on OS X 10.11 with conda:
$ conda create --yes -n testcase-tkinter-2 python=3.5 matplotlib
$ source activate testcase-tkinter-2
$ python -c "import matplotlib; matplotlib.use('TkAgg'); from
matplotlib import pyplot as plt"
objc[82465]: Class TKApplication is implemented in both
/System/Library/Frameworks/Tk.framework/Versions/8.5/Tk and
/Users/jlong/anaconda/envs/testcase-tkinter-2/lib/libtk8.5.dylib. One of
the two will be used. Which one is undefined.
objc[82465]: Class TKMenu is implemented in both
/System/Library/Frameworks/Tk.framework/Versions/8.5/Tk and

the two will be used. Which one is undefined.
Python still exits normally in this case.
Using the same environment, you can reproduce the exceptions we've been
seeing whenever plotting with TkAgg. Using Python interactively, we get:

And that's where it stands.
