I think TODOing the test is probably better than encoding a buggy output
into the test, since there's less risk that the change will remain
part of the test suite long after the bug has been fixed in tarantool.
The attached patch achieves this, and will NMU in a few days if we don't
hear from the maintainer.
Tested on sid, and the breakage is no worse than before.
I'm cloning this bug to tarantool to track the underlying problem.
Cheers,
Dominic.
