How can I disable the "Chromium didn’t shut down correctly" message when my browser opens?

I am running Chromium 39 on Ubuntu 14.04, on a single-board computer (ODROID U3, though I believe the question is applicable to Chromium on any Ubuntu system and possibly other Linux distros as well).

The computer is being used with Chromium in kiosk mode to power a large wall display; however, if the system loses power, when Chromium restarts it has the big nag bar complaining that "Chromium didn't shut down correctly". Since the system is designed to be automated, and we intend to run multiple systems, manually remoting into the machine (or worse, running around connecting and disconnecting a USB mouse) is not an acceptable solution.

How can I prevent Chromium from popping up this warning if it gets shut down improperly?

Much easier solution, start Chromium with the --disable-infobars flag. I tried all of the above before finding it, and it does exactly what I wanted. You can leave all of the other stuff alone.

My specific command line is:

/usr/bin/chromium-browser --start-fullscreen --disable-session-crashed-bubble --disable-infobars http://www.example.com

Also, apparently running in incognito mode by default will also prevent the error because nothing is saved from the session against which to check for a crash.

example: chromium-browser --kiosk --start-maximized --incognito kiosk.html
