[Python-modules-team] Bug#619193: [python-matplotlib] python-matplotlib: crash in py_to_agg_transformation_matrix

[Armin Berres]

Package: python-matplotlib
Version: 1.0.1-1

pytrainer is not really usable as it crashes all the time when it tries 
to render something with matplotlib.
To reproduce: Install and start pytrainer. Select File>New and create an 
entry with a random distance and a random duration.
Now try to switch to the week view and observe the crash. The backtrace 
looks like this:

#0  0x00007fffef9f6ae4 in __cxa_allocate_exception () from 
/usr/lib/libstdc++.so.6
#1  0x00007fffe3102ae4 in py_to_agg_transformation_matrix(_object*,
