Comment 27 for bug 1754646

It seems the issue was with the locale handling from libtextwrap. Both the newt and text plugins from cdebconf seemed to use textwrap() one way or another which was failing on mblen() when the locale was not correctly identified. This was causing all the <ERR> displays whenever an UTF-8 string was supposed to be wrapped and displayed in the installer. Colin remembered that in the past there seemed to be issues with the installation-locale C.UTF-8 locale requiring a rebuild against the newer glibc - and in this case it seemed to be the case indeed. Colin uploaded a no-change rebuild just now, so I would expect it to be good soon.
