import matplotlib.pyplot as plt is erroring for matplotlib-1.5.3 while trying to import from PyQt4.
I have observed this while running on Travis-CI, linux, installing matplotlib using conda. Here is a trace-back from the python 3.4.2 failure (https://travis-ci.org/simpeg/simpeg/jobs/160737799), for 2.7.9, there is an example in the travis log: https://travis-ci.org/simpeg/simpeg/jobs/160737812)

Thanks for your help!
