The 'value' field of the Config struct is defined in setup.h as:

      void *value; /* pointer to the real storage */

In the case for, let's say prefered_types, the value is set to point to the variable 'set_prefered_types' (around line 245 or so in setup.c).

When the contents of the value field is set to NULL, it is the variable that value points to that is set to point to NULL, in our example the 'set_prefered_types' variable is.

I agree it clearly looks like a bug, I'm not convinced it is at that particular place it gets wrong though.
