This problem was most recently seen with package version 0.9.1+17.04.20170216-0ubuntu1, the problem page at https://errors.ubuntu.com/problem/fcf5550475fb0478d6eb2a307f03705ef1ed398a contains more details, including versions of packages affected, stacktrace or traceback, and individual crash reports. If you do not have access to the Ubuntu Error Tracker you can request it at http://forms.canonical.com/reports/. 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.
