There should be absolutely no reason for Ubuntu have this plugin enabled
or even compiled. You might wanna file a bug to them to disable it. The
only place where it makes sense to be compiled is in Nokia's Maemo
Harmattan platform. For everything else it should be disabled (as it is
by default).

Btw, if you have your own RFCOMM based service you should take a look at
doc/assigned-numbers.txt to be sure not to conflict with any of those
services. The range of possible RFCOMM channels (1-31) is so small that
it's easy to get conflicts.

The plugin is called pnat, so that line should read DisablePlugins=pnat
