A possibly relevant bug-id:
http://bugzilla.quagga.net/show_bug.cgi?id=114

Incorporating this patch appears to fix the bug:
https://mail.new.datacore.ch/pipermail/dc-quagga-commit/2004-May/000051.html

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.  

<sarcasm>
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.
