When opening the launcher for the first time, I need to launch it twice

[jecisc]

On OSX El Captain, each time I install the PharoLauncher I need to launch it twice for it to open.

The first time it asks me if I am sure that I want to open an image coming from the internet, I click "open" and nothing happens. Then I relaunch it and it works.

Just to add to the issue, it happens too in Mojave (Just updated).

I've checked the system logs when the app is open and I have the following:

Nov  1 21:40:02 gotham com.apple.xpc.launchd[1] (com.apple.xpc.launchd.oneshot.0x1000000b.Pharo[1830]): Service exited with abnormal code: 1
