You must not run an application like this, I mean by referring directly its executable path.

Use launch (AppleScript) command with the application name or use Terminal open -a Chromium-Ghost. Both are commands to run an application as if clicking on its icon.

Clicking on an application icon does some over things than simply running the executable.
