+Subject: [PATCH] Fix crash when devices disappear during gdu_pool_new()
+
+It can happen that gdu_pool_new is running while a device is going away. A
+common case is when a program is listening to "volume-added" and calling
+gdu_pool_new() in its signal handler. In some cases like loop devices mounted
+to /tmp/, "volume-added" is sent on unmounting, immediately followed by
+"volume-removed" on removing the loop device.
