[Python-modules-team] Bug#585442: python-matplotlib: crashes when calling axis() after imshow()

[Teemu Ikonen]

Package: python-matplotlib
Version: 0.99.1.2-3
Severity: important

Running a program which displays an image with plt.imshow() and changes the
axes with plt.axis() before calling plt.show() crashes the python interpreter:

$ python mpl_crash.py
terminate called after throwing an instance of 'char const*'
Aborted

This happens at least with Qt4Agg, GTKAgg and TKAgg backends.

The example program is attached.

Best,

Teemu
