notice that the timestamps are different.  .vrrp was not recreated the
last time you started keepalived.  when you started it at 14:16 it did
work, no?

there is a race condition in the code, I think.  in my setup, it
"only" happens every fifth time or so I start keepalived.  my director
is a Dell PowerEdge 2650, with dual CPUs.  I suspect the dual CPUs are
aggravating the problem, but I haven't tried rebooting into a UP
kernel.

btw, upgrading to keepalived 1.1.1 will not fix this problem.  I do
however have a patch for keepalived which will fix a segmentation
fault which shows up as the same error in the log every time you
reload the configuration file.

also, consider joining the keepalived list -- this is more on-topic
there.
