I'm not sure what we should do about this.  invoke-rc.d doesn't seem to
sanitise the environment at all, so I imagine nearly all packages have
exactly the same bug.

Moving to Upstart would fix this, since with Upstart we can instruct the
init daemon to start the job rather than having to run the init script
as a descendant of the postinst.  I wonder if it's really worth going
around trying to sanitise the environment all over the place when we
should be able to switch to Upstart in the not too distant future
anyway?

Cheers,
