stack backtrace on boot

After recently upgrading, on boot I see this:

(then on to normal booting...)
Jul 26 15:07:59 neutrino lpd[532]: lpd startup: logging=1 net-secure
Jul 26 15:08:00 neutrino lpd[532]: lpd startup: ready to accept requests

I'm not sure what's causing this, but it doesn't seem to have broken 
anything that I can see right off.
