[Python-modules-team] Bug#610350: a font problem

[Picca Frédéric-Emmanuel]

When I try the test on my computer, I got this error message

~$ python -c "import matplotlib;matplotlib.test()"
...../usr/lib/pymodules/python2.7/matplotlib/font_manager.py:1242: UserWarning: findfont: Font family ['Bitstream Vera Sans'] not found. Falling back to Bitstream Vera Sans

When I compare generated / expected pictures, the difference seems to be the font.

PS: I already install the ttf-bitstream-vera package.

so maybe matplotlib could not find the installed font.

cheers,


Frederic
