Dear Maintainer,
blueman allows to share network access from the computer where it has been
installed. However, this assumes the presence of the standard 'iptables'
package. This pacakge is not installed by default as a dependence, and the
'exception' error message is a bit cryptic, when blueman attempts to use such
auxiliary package and does not find it available.

I suggest marking 'iptables' as a recommended or required dependence; or, as
secondary option which would require patching 'blueman-services', to clarify
its necessity in the error message when one tries to enable the functionality
'Network' 'NAP Support' 'Network Access Point (NAP).

If iptables is manually installed and blueman-services is restarted, everything
seems to be working fine.

Thank you!
