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.
