Merge lp:~fourdollars/ubiquity/xenial-proposed into lp:~ubuntu-installer/ubiquity/xenial-proposed

[Shih-Yuan Lee]

[Rik Shaw (rik-shaw)]

Is there any update on this update getting approved for xenial-proposed?

I just was tracking down strange behavior with crashes in ubiquity related to locale settings and I have confirmed this patch solves the issues (by manually applying the patch to the casper live system before running ubiquity).

Thanks for the work in solving this crash, now I am trying to understand how I can apply it to xenial for our re-spin installers (possibly similar to fourdollars mention of the dell-installer having issues and needing this patch)
