Fix null pointer dereference on strlen()

If string is NULL, then the proceeding strlen() on the string
will lead to a NULL pointer dereference error (segmentation fault).
Fix this by swapping the order of the comparisons, first check for
a NULL pointer; if that's not true then do the strlen check.
