Public bug reported:
I've installed xserver-xorg-xmir, unity8-desktop-session-mir, and set my
lightdm seat type to "unity". Using normal everyday unity-greeter and
unity7 session with xmir, most things work well.
The one thing that doesn't is trying to launch chromium. Doing so takes
down the xmir session entirely. Looking at the log file, I see:
