Category:	MySQL Cluster: Replication	Severity:	S2 (Serious)
Version:	5.1	OS:
Assigned to:	Pekka Nousiainen	CPU Architecture:	Any

Description:
NF (node failure) can send duplicate events
such as DEL o DEL, leading to assert in event code.
This kills a mysqld doing replication of tables
with blob attributes.

How to repeat:
NF + test

Suggested fix:
Weaken the assert.
Make event composition idempotent like replication itself.
