Please follow the Desktop Entry Specification (OnlyShowIn/NotShowIn)

Issue

Please follow the freedesktop Desktop Entry Specification standard.

Cinnamon has been a registered Desktop Environment since desktop-file-utils 0.23 which was released over a year ago (and I personally backported this change to Ubuntu 14.04 LTS).

Cinnamon clearly is an independent desktop and it's time for it to respect the OnlyShowIn and NotShowIn .desktop keys. Please drop your autostart-blacklist.

If an app incorrectly excludes Cinnamon, please file bugs for that. In the unlikely case that a patch would be rejected for that upstream, distros will accept your patches.

Example

Install Cinnamon on top of GNOME and you'll end up with 2 Files apps in your menu. (Do it in Ubuntu and you'll have 3 because of a unique Ubuntu packaging situation). This is silly since Nautilus sets OnlyShowIn=GNOME; (and the extra Ubuntu entry also should be hidden appropriately) and Cinnamon has its own file browser so this problem shouldn't exist.

Start with the session manager's handling of the autostart-blacklist, then read the linked Desktop Entry Specification sections for OnlyShowIn and NotShowIn. Trace how autostart desktop entries are filtered and verify that Cinnamon respects those keys without relying on the blacklist, including the duplicate Nautilus entry described in the example.
