I am encountering the following error:

python -c 'import pylab; pylab.clf(); pylab.plot(pylab.sin(range(101)));
pylab.xlabel("Test X"); pylab.ylabel("Test Y"); pylab.show()'

/local_home/calijos/usr/lib/python2.6/site-packages/matplotlib/backends/backend_gtk.py:621:
 DeprecationWarning: Use the new widget gtk.Tooltip
  self.tooltips = gtk.Tooltips()
Segmentation fault

-------------------------------------------------------------

But when I run the following command, I encounter no errors and plot is
as expected:

python -c 'import pylab; pylab.clf(); pylab.plot(pylab.sin(range(100)));
pylab.xlabel("Test X"); pylab.ylabel("Test Y"); pylab.show()'

I tried several other plots, any plots with less than 100 points work
correctly, any plots with more than 100 points segfault.

-------------------------------------------------------------

My current system setup is:

System: Ubuntu 9.04 x64
Python: Python 2.6.2
Matplotlib: >0.99.1 (tied 0.99.1.1, 0.99.1.2, and latest SVN version:
8126)
Numpy Version: 1.5.0.dev8106

I have been a long time Matplotlib user, and have never encountered this
issue.  It started whenever I updated numpy and scipy.  However,
reverting to the old version does not seem to fix the situation.  I also
cannot get numpy to crash on its own.  All my software works when
plotting is disabled.

Has anyone else experienced this or similar problems during an upgrade?

Joe
