Ok, access to the failing file is probably needed to sort this out.

I'm not able to access these -- maybe your institute has a firewall in 
between? You can also e.g. send the smaller file to me via mail.

There's no file named "test_array_import.py" in Scipy 0.8.0. You probably 
have some left-over files from Scipy 0.7.x in the directory. Anyway, the 
test suite seems to be in order.
