I think you mis-understood the problem I was reporting. You can find the
discussion thread here:
I have proposed that at the very least, an example of this problem is added
to the documentation of loadtxt so that users know to be aware of this
In addition, loadtxt fails on empty files even when provided with a dtype.
I believe genfromtxt also fails as well in this case.
