The second parameter is (as indicated by the exception) the radix[1].
With a radix of 2, 2 is written 10, as radix is binary. Radix 0 makes
no sense, and thus gives an exception.

It could be said though, that std.conv's documentation is confusing
at best, and this could be worth putting in Bugzilla.
