Hi all, I just stumbled on to what looks like issue CASSANDRA-2653. Here's my 
stack trace:

ERROR [ReadStage:10] 2011-06-27 15:22:36,087 AbstractCassandraDaemon.java (line

I am on version 0.7.6.

My question is, why is that ticket marked as minor? Does that mean most people 
are not encountering this problem on index queries? If that's the case I'd 
really like to understand the conditions under which this problem occurs so I 
can at least work around it. I am doing an indexslicequery, specifying a column 
family, a single column name and an equals expression. For my client, I'm using 
hector version 0.7.0-29.

I'd also like to know when this bug is expected to be fixed and when 0.7.7 
might be released. I have 0.7.5 running in production right now and I really 
need an upgrade to resolve different bug.

Thanks,
Shu
