Package: python3
Version: 3.5.1-2
Severity: important
Control: block 796061 by -1
Hi
apt-listchanges contains code like:
sys.stdout.write(_("Reading changelogs") + "...\n")
In pl_PL.UTF-8 locale the python3 version of apt-listchanges (from bug#796061)
such a line causes the program to fail with
TypeError: can't concat bytes to str
Surprisingly the no error is returned when locale is C.
In my opinion this is a serious mis-design of gettext.lgettext() which
prevents me from performing the migration of apt-listchanges to python3.

Traceback (most recent call last):

'Informational notes\n'
