polkit's pkexec replacement for gksu/gksudo, does not work in unity,
nothing appears to happen. The error can be seen by launching Ubuntu
12.04 or 12.10 (and possibly 13.10), opening a terminal, and typing
"unity --replace", then launching an app requiring pkexec in the dash.
The error "Refusing to render service to dead parents." is shown upon
launch, and nothing appears to happen on the desktop. I can confirm this
happens in both Precise and Quantal, and perhaps (untested) in Saucy. It
doesn't happen in Trusty, as of 30 Jan. This affects quite a few
applications, and prevents them from running, and also affects mine. For
the mean time I'll fix it by using gksudo in my .desktop files for
Ubuntu only, but it's only a matter of time until gksudo is deprecated,
and removed from the PPAs. Update: if you adopt gparteds method from a
bash script, it does work.
