We hit this issue while testing 11.1R1, and oh what a mighty big screwup it was on Juniper's part too (that it even tries to parse the packets that are killing it in the first place, when NOT CONFIGURED TO DO SO, simply boggles the mind). Unfortunately it's also not the only "packet of death which crashes the FPCs" issue in 11.1 on EX, we also discovered another one which DIDN'T get fixed in 11.1S1, so you're taking your life into your own hands if you try to run that code in production. Oh and BTW, 11.1 on EX will also blackhole your packets while BGP converges following bootup, for up to 15 minutes in our testing. Consider yourselves warned. :)
