+ It seems that the configuration change is requested just a moment before
+ the device gets removed. The change actions are serialized, depending on
+ where there memory of mir::input::DefaultDevice is allocated the
+ segfault either occurs inside the lambda or inside underlying
+ mir::input::LibInputDevice in the platform. The activities on input
+ dispatch device removal and reconfiguration are serialized inside the
+ input thread, so we just need to clean the action queue (or have
+ multiple queues) before removing the devices.
