And with my continuing saga of backend-specific things...
I was using conda, but because it does not ship with pygtk support, I had
to manually install pygtk into the conda environment and then install
matplotlib from source. All that seemed to work fine when I worked on Wx
and Gtk examples for my book.
I went back to a (previously working) Tk example to polish it, and I get
all sorts of errors now. I have tried multiple releases of matplotlib from
source (doing a git clean -fxd between them), all with similar errors. In
fact, with master, the error causes a segfault:
ben@tigger:~/Documents/InteractiveMPL$ python chp5/slider_tk.py
Exception in Tkinter callback
Traceback (most recent call last):

TclError

The line in question is (at least in v1.3.1, it is slightly different in
more recent versions):
tk.call("PyAggImagePhoto", photoimage, id(aggimage), colormode,
id(bbox_array))
This happens regardless of what example I use (my own or otherwise). There
is no blit-specific code in the examples. All of this worked with the
conda-supplied matplotlib, but never the
from-source-into-a-conda-environment install.
Thoughts?
