Well, what I meant with that change was that the functions used for data
delivery changed. Specifically:

Analyzer::{NextPacket, NextUndelivered, ForwardPacket, ForwardUndelivered,
DeliverPacket, Undelivered} were modified to change the int seq parameter
to a uint64. If your functions aren't updated, and are expecting a plain
old int for the sequence number, I've seen the scenario you describe: the
analyzer attaches, but doesn't function.
