Package: python-matplotlib
Version: 0.98.1-1
Severity: serious
The current version of python-matplotlib in debian testing and lenny
has a number of serious bugs and omissions
* Bug: memory leak using shared axes (attached script looptest.py
shows the leak)
* Bug: transforms method offset_copy missing -- this breaks
examples/pylab_examples/transoffset.py
* Omission - the doc directory was omitted from the 0.98.1 MANIFEST
These are fixed in matplotlib svn r5907
