  What do you mean by "then check if it's crash"? Surely we should do nothing and let LIBMTP sort out printing errors and stuff? Eventually the device should be reclaimed by the daemon anyway via the help of `Solid::deviceRemoved()`. I agree with everything after the comma though, `LIBMTP_mtpdevice_t *` should never be freed unless we explicitly do so ourselves.
