I do nit think that the issue can be explained by a missing
Build-Depends - otherwise it would fail in pbuilder as well IMHO.

In the past I made good experiences by setting
   export LC_ALL=C.UTF-8
in debian/rules - but this neither had the effect to make the package
fail in my pbuilder nor let it build in your sbuild environment.

I kept on trying rather on your sbuild environment.  Finally I decided to
ignore the failure of this single test by this change:

While I'm definitely not proud about this solution it is the only one I
could provide for the moment.  Its a bit hiding the eyes style and may
be patching the very test that currently fails gives some more safety to
potential other failures that will be overlooked.  On the other hand
further higher level tests are running after the ignored test - so real
breakage will be detected in any case.

I'd be in favour of to start working on the latest upstream release
rather than solving riddles on the old code.  We might come back later
if this issue might persist.

What do you think?

Kind regards

      Andreas.
