variable `munin_node_allowed_cidrs` wrongly templated?

[logiczny]

Hi, I love your work and I use many of your projects daily!
I've noticed that when I setup a variable per host (in hosts.ini) like so:
192.168.1.3 munin_node_allowed_cidrs=192.168.1.2/32
or
192.168.1.3 munin_node_allowed_cidrs=[192.168.1.2/32]
or even
192.168.1.3 munin_node_allowed_cidrs=[ 192.168.1.2/32 ]

I'm getting something like this in 192.168.1.3's munin-node.conf:

(...)
cidr_allow 1
cidr_allow 9
cidr_allow 2
cidr_allow .
cidr_allow 1
cidr_allow 6
cidr_allow 8
cidr_allow .
cidr_allow 1
cidr_allow .
cidr_allow 2
cidr_allow /
cidr_allow 3
cidr_allow 2
(...)

instead of
cidr_allow 192.168.1.2/32

When I setup a variable in a role at a playbook - it works like expected, but I need different IP addresses per host.
Am I doing something wrong here?
