--- Comment #1 from Michael Catanzaro <mcatanzaro at igalia.com> ---
Note that this is a *UI process* assertion. Apparently image decoders are used in the UI process for the favicon database. This is surprising and unexpected to me, since I would not expect this security-critical code to be running in the UI process. I suppose we need to render those favicons somehow, but it should happen in a constrained secondary process where only the result is passed back to the UI process. This is what we do in gdk-pixbuf now, so that the image decoders can be sandboxed with seccomp filters. Of course, that's a much larger challenge for another bug report... in this bug we should just fix this assertion.
