At a glance, I'm not sure it's unrelated. And I say that wanting to give you the benefit of the doubt. Your bug does spend some time enumerating a permission problem that is covered by the first comment on the master question:
These actions were for ConsoleKit. logind has its own rules, so you need to rewrite them to enumerate org.freedesktop.login1.suspend and org.freedesktop.login1.hibernate (see /usr/share/polkit-1/actions/org.freedesktop.login1.policy).
The rules have moved. Here's another bug report that goes over the same ground. I know you've seen this before but I want to make sure it's clear, this is the sort of code you want:
# cat /etc/polkit-1/localauthority/90-mandatory.d/disable-suspend.pkla
[Disable suspend by default]
[Disable suspend for all sessions]
If that's not enough (either it not working or nor suppressing the menu item, or some mix of the two), edit your bug description and make it super-extra clear that your issue is with the indicator... And then shunt it back to confirmed (or whatever it was before.
In general terms though, you have to look at the bug in question and work out whether or not the master version (or any others linked to it) actually describe or are the source of your problem. If they're not, make that as clear as possible and reopen.
