[matplotlib-devel] figure error during python shutdown

[Benjamin R. <ben...@ou...>]

There seems to be an odd error that comes up when exiting python after using
matplotlib with gtkagg backend.  I only notice this error if I do not
display the figure (i.e., only saving figures in a headless mode) and during
the test.  Also, this is with matplotlib master branch.  I have not tested
this with any other branch.  Here is the error message:

Error in atexit._run_exitfuncs:
Traceback (most recent call last):
  File "/usr/lib/python2.6/atexit.py", line 24, in _run_exitfuncs
    func(*targs, **kargs)
  File "/home/bvr/Programs/matplotlib/lib/matplotlib/_pylab_helpers.py",
line 82, in destroy_all
    manager.destroy()
  File

    self.canvas.destroy()
AttributeError: FigureManagerGTKAgg instance has no attribute 'canvas'
Error in sys.exitfunc:

This happens with both python 2.6 and 2.7.  I have not tested any other
version.
