It seems xvidcore overreads its input buffer, so a nasty workaround is to allocate some more memory (16 bytes seem to be enough). There is no apparent image corruption with these extra bytes set to 0, valgrind is much happier, and the crashes go away. It is ugly, and slower though. But then, xviddec is currently not autoplugged for playback anyway. https://bugzilla.gnome.org/show_bug.cgi?id=334107
