gnunet-gtk is basically the last thing in Debian using glade. The
Debian GNOME team would like to remove glade from Debian because it is
unmaintained.

We may ultimately need to remove gnunet-gtk from Debian because of
this issue. gnunet-gtk has no reverse dependencies, is orphaned, and
has low popcon. On the other hand, the project is still maintained
upstream and looks like it could be useful to some people.

Thank you,
