What steps will reproduce the problem?
1. run the attached script, look at beautiful wavefunctions
2. change "Neig" from default 6 to anything else
3. See everything fail miserably. With a bit of luck, you'll see terrible 
solutions, otherwise, ARPACK complains about no solutions found.

What version of the product are you using? On what operating system?
WinPython-64bit-3.3.2.0

Please provide any additional information below.
It also fails when using eigsh.
The same script works fine on Arch's Python3.

Installing another build of scipy, 
http://www.lfd.uci.edu/~gohlke/pythonlibs/#scipy
and installing that using the winpython package manager fixes this issue.
