I see: your list has 50 entries.
And indeed the C code says:

        [...]
	else if (STRINGP (car) || CONSP (car))
	  {
	    register int limit = 50;
	    /* Limit is to protect against circular lists.  */
        [...]

so it looks like you bumped into a hard-coded limit.
I've just installed the patch below which should move the hard limit far
enough for now.
