Fix another delete[]/free problem. 

This patch fixes a delete[] vs free problem in the NexusSet
class. The items_ array was being allocated with malloc/realloc
and freed with delete[]. The quick fix was to replace delete[]
with a call to free(). A better fix would probably be to rework
the class to use a vector.
