I'm running Ubuntu 16.04.3, my Unity was crashing in a similar way as it was originally described in this bug. Installing libgl1-mesa-dri/xenial-proposed fixed the issue. However, today, I tried to install Steam and it failed, at least partially, because the system is not being able to install libgl1-mesa-dri:i386 and libgl1-mesa-glx:i386. This seems to be related to the installation of libgl1-mesa-dri/xenial-proposed.
These are the messages I see in the terminal when trying to open Steam for the first time:
