wmem_array_index() returns a *pointer* to the array element.

The array is an array of guint8 *'s that point to strings;
wmem_array_index() doesn't return a pointer to the string, it returns a
pointer to a pointer to the string, and you have to dereference the
result of the wmem_array_index() call to get a pointer to the string.
