You may have old apt-listchanges pyo/pyc files in
/usr/share/python/site-packages or sth similar. Look for
apt_listchanges.py{o,c} on your system, the ones in
/usr/share/apt-listchanges/ are OK and normal, the other ones are not.
If that's the case, then you probably messed up something on your
system and is not a packaging bug (I do remove the old pyc/pyo the old
apt-listchanges created at preinst time).
I can't see any other reason, because the "pager" frontend inherits
the "frontend" class that _do_ have a set_title member.
Well, these files were kept in /usr/lib/site-python and I don't really
know why... It doesn't really matter since I removed them, and
apt-listchanges is working correctly now...
Sorry for the inconvenience, this bug could be closed :)
