Hello,

Yesterday I broke cinnamon and nemo I believe by deleting wrong menu entries.

Steps to reproduce :

1. Right click the menu icon > Configure...
2. Switch to the menu tab
3. Click "Open the menu editor"
4. Select the category "Other"

From here I thought first the names in italic font were safe to delete since when I select one, the Delete button is enabled as shown in the picture below.

This was a disastrous idea I think because after doing so and after a system restart, cinnamon and nemo-desktop failed to start at all, no more panels, no more desktop icons, I needed to start manually cinnamon --replace and nemo-desktop to partially recover.

And to fully recover the automatic boot, I have deleted all the files in /home/arno/.local/share/applications

To note that the button of menu@cinnamon "Restore System Configuration" did not help for recovering this case, since this was my settings overriding the default system settings.

Steps to fix :

I suggest that, when a user selects a system entry in italic font, the Delete button should be disabled for preventing any wrong usage as I have done, because this was not very easy to fix all this by myself, I was close to reinstall everything haha.

Hope you understand :)
