Comment (by klee):
The cause of the second issue is explained in the Python doc about
`__del__` method, which is used in the class `LatexManager` in the
`.../lib/matplotlib/backends/backend_pgf.py` file. The method tries to
close temporary files whose list is kept in the class attribute
`_unclean_instances`, by calling `_cleanup(self)` method, which in turn
uses the `os.path` module. But as Sage is shutting down, the last module
is in state of being destroyed. Thus an exception raises (but ignored).
Simply speaking, the `__del__` method is doing too much at a critical
moment.
I don't know the appropriate way of dealing with this (bug?). Should it be
dealt in Sage or at upstream?
