astropy: Intermittent segfaults with ascii loader

My python interpreter crashes with a segfault about 10% of the time when I try to run

In [1]: from astropy.table import Table
In [2]: Table.read('test.csv', format='ascii')

when called using this file

the original file is about 10x larger, and it crashes everytime. I haven’t been able to track down much more information than that. It doesn’t crash if I don’t set format=‘ascii’
