Yes, I agree. There were multiple issues going on, some of which have
been fixed. Here is my take on the matter: Some package in
ubuntu-desktop has similar behavior to what xfce4-power-manager used to
have, that is, it doesn't explicitly hide its icon. It is different,
however, as killing xfce4-power-manager was enough to fix it, whereas I
am pretty sure that killing just that mysterious process from
ubuntu-desktop deps is not sufficient: It might have already exited by
the time the signal to add an icon reaches lxpanel.

I have no idea how to find which process that is, and thus gain an
understanding of what is going on. Commit 1604938f0 in lxpanel does not
prove useful for this. (Although this bug is the reason it was added,
and 82ca42af43b6, too.)

Unfortunately, I don't have time to work on this right now.

Good luck,
Henry
