--- Comment #1 from Michael Catanzaro <mcatanzaro at redhat.com> ---
So AcceleratedBackingStoreDMABuf::frame calls FenceMonitor::addFileDescriptor with renderingFenceFD = 0, which is illegal. And the bogus fd is coming directly from the web process.

This shouldn't result in a UI process crash, though. It should result in a web process kill. We are missing MESSAGE_CHECK() here.
