Code for reproduction
In [1]: import matplotlib as mpl
In [2]: mpl.use('TkAgg')
In [3]: import matplotlib.pyplot as plt
In [4]: plt.plot([0, 1])
Out[4]: [<matplotlib.lines.Line2D at 0x7fb09f2a0350>]
In [5]: plt.show()Actual outcome
Closing the window does not return control to iPython
Matplotlib version
- Operating System: Linux
- Matplotlib Version: 1.5.3
- Python Version: 2.7
- Other Libraries: iPython 4.1.2, but it happens with other versions too.
Installed via conda via conda-forge channel
The issue doesn't occur in 2.0. Are there likely to be any more 1.5 point releases?

Unfortunately there won't be any more 1.5 point releases, so upgrading to 2.0 is the best option. (is there a reason you're still using 1.5 and not 2.0?)

In IPython it is generally recommended to use the %matplotlib magic such as %matplotlib tk if you are stuck on 1.5.3 I would recommend trying that

calling plt.ion() should also fix the problem (by making plt.show() non-blocking).
Closing as there will be no more 1.5.x releases and is reportedly fixed in 2.0
