+  [ Iain Lane ]
+  * debian/rules: Set HOME to the real home directory for the test. This might
+    not be set right when building the package, but one of the tests looks up
+    ~user and checks that it corresponds to $HOME, so we need to make sure it
+    is.
+  * src/main.vala: Don't call set_desktop_env(). It's not needed with modern
+    GLib, and prevents XDG_CURRENT_DESKTOP from being used.
