I get a mysterious problem when I try to upgrade from 87.2 to 87.3.
At first it complained of a bad configuration file. Once that was corrected, though, matplotlib still crashes Python as soon as "import pylab" or "import matplotlib" is called. No message of any kind is passed.
The Windows error report says the exception was in multiarray.pyd. I can reinstall 87.2 and everything is fine. Any idea what the problem might be?
