NullPointerException from o.a.c.db.ReplicateOnWriteTask
-------------------------------------------------------

                 Key: CASSANDRA-1903
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-1903
             Project: Cassandra
          Issue Type: Bug
          Components: Core
            Reporter: Eric Evans
         Attachments: thrift-test.py

I'm seeing a whole lot of these when writing to a node.

java.lang.NullPointerException
	at org.apache.cassandra.db.ReplicateOnWriteTask.run(ReplicateOnWriteTask.java:97)
	at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1110)
	at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:603)
	at java.lang.Thread.run(Thread.java:636)
{noformat}

I don't think it will be difficult to reproduce, but the script I'm using is attached.

I bisected the source tree and and http://svn.apache.org/viewvc?view=rev&revision=1052356
seems to the culprit (a merge from 0.7).  Maybe CASSANDRA-1530?
