Your script is line wrapped in your post, so it is difficult to know
exactly what you mean. The following does not segfault for me
from matplotlib.matlab import ylabel
ylabel('bia [cm]')
raw_input('continue')
ylabel('Bia [cm]') # seg fault
raw_input('continue')
It would be helpful if you narrowed the scope of your problem by using
the Agg backend. My guess is you'll encounter the same problem.
Assuming so, there are two extra things you could do to give more
information
Edit site-packages/matplotlib/backends/backend_agg.py in the function
_get_agg_font, print the font filename you are using. Ie, on or
around line 231 in matplotlib-0.61, add the print line as below
if font is None:
fname = fontManager.findfont(prop)
print 'agg loading', fname
try: font = FT2Font(str(fname))
Additionally, you may want to set at the top of that file
DEBUG = 1
and edit setup.py and set
VERBOSE = True
and recompile matplotlib cleanly. To do this, go to the matplotlib
src dir and 'rm -rf build' before reinstalling matplotlib.
Rerun your tests - be prepared for a deluge of messages.
This should provide some additional helpful information.
You may want to followup to the devel list instead of the users list
Thanks,
