I think that gphoto2_backend->lock is also not NULL, as g_mutex_clear()
derefs it: g_mutex_impl_free (mutex->p); it seems it's
gphoto2_backend->lock->p which is NULL then, i. e. the mutex was not
initialized properly.
The only access to this aside from the _lock()/_unlock() calls is in
do_mount() line 1715, i. e. it gets initialized _after_ release_device()
is called (which tries to free it again).
