No, this is correct.  A capacity of zero simply means the slice cannot be
appended to.

http://dlang.org/phobos/object.html#.capacity

If an append must reallocate a slice with no possibility of extension, then 0
is returned. This happens when the slice references a static array, or if
another slice references elements past the end of the current slice.
