The issue is fixed in the raring version, we should probably backport the commit to precise as well: https://git.gnome.org/browse/gtk+/commit/?h=gtk-2-24&id=85825ebaf2c16bb48602d5d3ced5e9ecd6605852

(the authentication dialog pops up once, but the client only sends an empty password to the server after that). This was fixed in the upstream Gtk3 branch some time ago (commit f807f7834fea0db7b0b68cd1a0dfa3dbe0985ec2), but still hasn't been applied to the Gtk2 branch. The upstream bug report is https://bugzilla.gnome.org/show_bug.cgi?id=664640 I have confirmed that the Gtk3 patch also fixes the problem for Gtk2; it would be nice to have the fix included in the Precise Gtk2 packages as I need this feature to work. It probably also affects other Ubuntu releases.
