--- Comment #2 from Michael Catanzaro <mcatanzaro at igalia.com> ---
I'm not sure how we try to register the type twice, but it looks like this is only a problem for in-process plugin scanning, which only I use because we only do this with seccomp filters enabled. And we need to stop doing in-process plugin scanning before we turn on seccomp filters by default, see bug #140131 which is a priority for me. So, I won't bother any further with this.
