frontend=gtk broken after upgrade to maverick

[alm]

Binary package hint: apt-listchanges

After upgrading from lucid to maverick, apt-listchanges no longer honors the pager=gtk setting in /etc/apt/listchanges.conf (attached), at least when run from update-manager (haven't tested plain aptitude yet, will do when next update becomes available). It displays the changes in $PAGER, which means update manager will wait until you click on details and exit less. The dependencies for pager=gtk indicated in the man page are installed, and it used to work in lucid:
ii python-glade2 2.21.0-0ubuntu GTK+ bindings: Glade support
ii python-gtk2 2.21.0-0ubuntu Python bindings for the GTK+ widget set

Does work properly with aptitude. Did update-manager start using a different profile? In that case, the default configuration might have to be updated, and this change should be documented somewhere (unless it already is and I just missed it).

Could this be a duplicate of Bug #227652?
