Subject: Also catch RuntimeError when importing pyplot in pid_response.py.
X-Git-Tag: v0.3^0
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=8010c347226bcbb22123a89c4ac2d8676612cd19;p=pypid.git

Also catch RuntimeError when importing pyplot in pid_response.py.

In case matplotlib is installed, but poorly configured for your
current situation.  For example, if you've SSHed into a host without
tunneling X, you can see:

  $ python -c 'import matplotlib.pyplot'
  /usr/lib/python2.7/site-packages/gtk-2.0/gtk/__init__.py:57:
    GtkWarning: could not open display
  ...
  RuntimeError: could not create GdkCursor object
