Comment 1 for bug 410241

I'll take the gnome-session task. The fix will be a combination of removing "include /usr/share/gnome-pkg-tools/1/rules/patch-translations.mk" from debian/rules and ensuring that any extra translatable files introduced in the debian directory are listed in po/POTFILES.in (although I'm not sure this applies for gnome-session, as the only extra translatable strings are in 10_session_save.patch which only touches an already translatable file).
