Duplicate ipsets listed with Locationblock changes.

If I list the installed ipsets with 'ipset -n list' additional ipsets with the suffix 'v4' are sometimes listed. From what I can see this additional 'v4' list is the same size as the set without the 'v4' extension.

For instance: with just code AR selected with location-block.cgi:

[root@ipfire-dev2 ~]# ipset -n list ARv4 AR (code AR id duplicated)

if I add code AT to AR and list the sets: [root@ipfire-dev2 ~]# ipset -n list AT AR (as expected)

and now add code AW to the other 2: [root@ipfire-dev2 ~]# ipset -n list ARv4 AT AR ATv4 AW (now codes AR and AT are duplicated)

I see this effect on both my core 167 boxes and wasn't aware of this problem before my upgrade from core 161.
