Ack.

So, something on your local system is interfering with the test. schroot
and lxc are better in setting up a clean environment than the null runner.

How about other environment variables? (Or fonts, see below)

I'd say the opposite. schroot's and lxc's generated with autopkgtest are
cleaner than your own computer. Of course there's still something, so
let's try to find out.

To my eye it looks like a font (or more) is (are) missing in the
testbed. fonts\$name\[2\] does not match "MSung" and fonts\$name\[3\]
does not match "MHei" suggest to me that something needs to provide
them. Maybe that would fix the first issue too.
