You seem to have a bunch of newlines removed. Considering how rancid
works, it's hard to imagine that the bug is happening inside rancid
itself, so maybe the device itself is doing it? But, the previous time
rancid ran, it parsed the input correctly. Interesting....


What kind of device is this, what rancid version are you using, and what
device type have you configured the firewall as?
