+Subject: [PATCH] udisks2: Disconnect signal handlers before freeing data
+
+After the commit 1b80450a, the udisks2 volume monitor crashes sometimes after
+showing the unmount notification. This is because the `UnmountNotifyData`
+struct is freed, but signal handlers are still connected. Let's disconnect
+the signal handlers to avoid those crashes caused by invalid reads.
