A possibly relevant bug-id:

Incorporating this patch appears to fix the bug:

Routers running with the above patch have not been affected.

The same type of people who experienced crash due to unknown ecommunity, at
least on our network I believe have upgraded their software.  

To again verify the operational success of this patch, may be AS5430's
downstream who announced this prefix before can try announcing the route
again and see if bunch of things crash? ;-)

$2 says nothing will crash this time.
