Some more news, I added printing of stack trace to perl's client, and I see that
problem is in getting answer from server, not in sending. It breaks on reading
of exception (TMessageType::EXCEPTION) from server side.
Cassandra outputs (with loglevel DEBUG):
DEBUG - get_slice_from
ERROR - Internal error processing get_slice
java.lang.NullPointerException
