Description
I am trying to use matplotlib inside a Docker container running as non root. When I do I get the following:
$ docker run -u 5001 -it 4catalyzer/ipython python -c 'import matplotlib'
Traceback (most recent call last):

tempdir = os.path.join(tempdir, 'matplotlib-%s' % getpass.getuser())
File "/usr/lib/python2.7/getpass.py", line 158, in getuser
return pwd.getpwuid(os.getuid())[0]
KeyError: 'getpwuid(): uid not found: 5001'
Potentially just have getpass.getuser() then fall back to the UID value.
