When launching mintsources, timeshift or an app which Exec field (in the desktop file) starts with pkexec, nothing happens and the output states: "Refusing to render service to dead parents." For some reason this does not happen on fresh LMDE 4 and Mint 19.3 installations, but it happens on LMDE 3 -> LMDE 4 and 19.1 -> 19.3 upgrades. Similar bugs were fixed in nemo and cinnamon. Pkexec is known to cause issues depending on how it's launched. This introduces a workaround to wrap the pkexec call within an "sh -c".
