+Subject: [PATCH] Revert "[mate-bg] small cleanup"
+
+It is not possible to use the `list` pointer after it has been deleted,
+so the "cleanup" this commit made lead to using freed memory if any
+item actually got clean up.
+
+This "cleanup" also don't seem meaningful to me, as all it does
+otherwise is trade an assignation for a redundant test -- either of
+which the compiler might happily optimize out.
+
+This reverts commit 47426c90d10e9f738ecf89f35db94ca8deff55e0.
